ratio 90kg to 2 : 3 : 7

Answer:

45 degrees

Step-by-step explanation:

135+135=270

360-270=90

90/2=45

your answer is 45 degrees

Answer:

Step-by-step explanation:

Two angles form linear pair if they are adjacent angles and their non common arms are opposite rays.

Corresponding angles: When two parallel lines are intersected by the transversal, the angles formed on the matching corners of the same side of the transversal are called corresponding angles.

∠1 + ∠2 = 180°   {Linear pair}

135 + ∠2 = 180

        ∠2 = 180 - 135

∠2 = 45°

∠6 = ∠2   {Corresponding angles}

∠6 = 45°

Answer:

19 terms

Step-by-step explanation:

the sum to n terms of an AP is

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]

where a₁ is the first term and d the common difference

here a₁ = 18 and d = a₂ - a₁ = 16 - 18 = - 2, then solving for n

[tex]\frac{n}{2}[/tex] [ (2 × 18) - 2(n - 1) ] = 0 ( multiply both sides by 2 to clear the fraction )

n(36 - 2n + 2) = 0

n(38 - 2n) = 0 ← distribute parenthesis on left side by n

38n - 2n² = 0 ← factor out 2n from each term on the left

2n(19 - n) = 0

equate each factor to zero and solve for n

2n = 0 ⇒ n = 0

19 - n = 0 ⇒ n = 19

n > 0 , then number of terms is 19

x=37.8

Step-by-step explanation:

According to Pythagoras theorem

AB = 21.5

BC = 13.1

AC = ?

AC²= AB²+BC²

x² =(21.5)²+(13.1)²

x² =462.25+967.21

x² =1429.46

x =√1429.46

x =37.8

Answer:

Answer:

x = 7

Step-by-step explanation:

=> x = 7

Step-by-step explanation:

p=1500

R=10%

t=20yrs

SI=PTR/100

Answer:

It is not true

Step-by-Step:

^ABC, m<A = 119 degrees.

In triangle ABC, side BC is longer and side AB shortest side.

Given that, in ΔABC, m∠A = 119° and m∠B = 49°.

The triangle inequality theorem describes the relationship between the three sides of a triangle. According to this theorem, for any triangle, the sum of lengths of two sides is always greater than the third side.

Using angle sum property, we get

m∠A+m∠B+m∠C=180°

⇒ 119°+49°+m∠C=180°

⇒ m∠C=180°-168°

⇒ m∠C=12°

So, using triangle inequality theorem opposite to angle A, side BC is longer and opposite to angle C, side AB is shortest side.

Therefore, in triangle ABC, side BC is longer and side AB shortest side.

I do see D(4-1) and C(-3,4).  The question asks what is the midpoint.  That would be point M, with a coordinate of (0.5,1.5), which is derived from the average of the two points:  x: (4-3)/2 = 0.5; y: (-1+4)/2) = 1.5

See the attached image for how the points relate to each other.  I derived an equation for the point to illustrate where the midpoint, M, is situated.

=============================

Slope = Rise/Run

Rise:   (-1 - 4) = -5

Run:    (4 - (-3)) =  7

Slope = -(5/7)

Equation for the line is y = -(5/7)x + 1.9

Answer:

One

Step-by-step explanation:

     Since we have a 90° angle and a 20° angle, the last angle must be 70°.

180° - 90° - 20° = 70°

     Now we also have the requirement of a 6-unit side between the 90° and 20° angles.

     With all of these requirements, we can only draw one triangle like this since we have an angle, an angle, a required third angle, and a side.

The difference between the maple and oak trees is the difference

between  [tex]28\frac{2}{6}[/tex]  and ([tex]11\frac{3}{6}[/tex] + [tex]7\frac{5}{6}[/tex] ), which is 9 yards.

Response:

The distance between the maple tree and the oak tree is option B.

B. 9 yards

The given parameters are;

Start → Maple tree → Oak tree → Pine tree → End

The distance from the start to the maple tree = 5 yards

The distance from the maple tree to the end = [tex]\mathbf{28\frac{2}{6}}[/tex] yards

Distance from the oak tree to the pine tree = [tex]11\frac{3}{6}[/tex] yards

Distance from the pine tree to the end = [tex]\mathbf{7\frac{5}{6}}[/tex] yards

Required:

The distance between the maple tree and the oak tree

Solution;

From the maple to the end, d is given as follows;

d = Maple tree to the end - Distance from the oak tree to the end

Oak to the end = Oak to pine + Pine to end

Therefore;

[tex]Oak \ to \ the \ end = 11\frac{3}{6} + 7\frac{5}{6} = 19\frac{1}{3}[/tex]

Which gives;

[tex]Maple \ to \ the \ oak \ tree = 28\frac{2}{6}- 19\frac{1}{3} = 9[/tex]

The distance from the maple to the oak tree = 9 yards

The correct option is; B. 9 yards

The ratio of rise to run, which is the slope between the two points is: -1/4.

Slope = ratio of rise to run = change in y/change in x

Given the following points:

(-10, 9) and (6, 5)

Rise = (5 - 9) = -4

Run = (6 -(-10)) = 16

Ratio of rise to run = slope = -4/16 = -1/4.

Therefore, the ratio of rise to run, which is the slope between the two points is: -1/4.
