For positive acute angles AA and B,B, it is known that \sin A=\frac{8}{17}sinA= 17 8 and \cos B=\frac{24}{25}. CosB= 25 24 . Find the value of \sin(A+B)sin(A+B) in simplest form
Answer:
sin(A+B) = 297/425
Step-by-step explanation:
This problem involves a couple of Pythagorean triples, and the trig identity for the sine of the sum of angles.
The Pythagorean triples involved are {8, 15, 17} and {7, 24, 25}. These tell us the other trig functions of the given angles:
sin(A) = 8/17 ⇔ cos(A) = 15/17
cos(B) = 24/25 ⇔ sin(B) = 7/25
The trig identity we're using is ...
sin(A+B) = sin(A)cos(B) +cos(A)sin(B)
sin(A+B) = (8/17)(24/25) +(15/17)(7/25)
[tex]\sin(A+B)=\dfrac{8\cdot24+15\cdot 7}{17\cdot25}\\\\\boxed{\sin(A+B)=\dfrac{297}{425}}[/tex]
_____
Check
A = arcsin(8/17) ≈ 28.072°
B = arccos(24/25) ≈ 16.260°
sin(A+B) = sin(44.332°) ≈ 0.6988235
sin(A+B) = 297/425

Ellen purchased a dishwasher, which cost $315 before the 9. 22% sales tax.
She used the machine an average of 10 times per week for the next six years, at which point she replaced it.
Each time she ran the dishwasher it cost her $0. 09 for water and $0. 13 for electricity.
The cost of a dishwasher after sales tax will be
Cost = 1.0922 × 315 = $ 344.043
The running total time of dishwasher in 6 years will be
Total running time = 10 × 52 × 6
Total running time = 3120
She ran the dishwasher 3,120 times in 6 years.
The cost of water in these six years will be
Cost of water = 0.09 × 3120 = $ 280.8
The cost of electricity in these six years will be
Cost of electricity = 0.13 × 3120 = $ 405.6
The entire cost is the sum of the dishwasher after sales tax, water, and electricity will be
Entire cost = $344.043 + $280.8 + $405.6 = $1030.44

Euler's formula, V – E + F = 2 relates the number of vertices V, the number of edges E, and the number of faces F of a polyhedron. How many faces does a polyhedron with 5 vertices and 8 edges have?
Answer:
V + F - 2 = E
Step-by-step explanation:
V - E + F = 2 --- add E to both sides
V + F = 2 + E --- subtract 2 from both sides
V + F - 2 = E

Teresa has 800 milliliters of water. Sara has 5 liters of water. Without converting units, tell why Sara has more water than Teresa. Then show how much more water more Sara has.
Answer:
Step-by-step explanation:
You can't do this without some conversion of units. You can do it with just the definition of a Liter
1 Liter has 1000 mL
1000mL > 800 mL
5 Liters requires a conversion
5 Liters = 5 * 1000 = 5000 mL
Difference = Sara - Teresa use to determine how much more Sara has
Difference = 5000 - 800
Difference = 4200
Sara has 4200 more mL than Teresa
What is the value of x?
The value of x is .
Answer:
38*
Step-by-step explanation:
verticle angles are always going to be equivilent so the opposite of x is 38 so x also =38
The measure of angle x from the intersecting lines is x = 28°
What are the angles formed by 2 intersecting lines?Two straight lines that intersect at the same location are said to be intersecting lines. The junction point is the place where two intersecting lines meet. Four angles are created when two lines cross. The four angles added together always equal 360 degrees.
Perpendicular lines are two straight lines that intersect and form right angles. When two perpendicular lines intersect, they form four right angles.
When lines intersect, two angle relationships are formed:
Opposite angles are congruent
Adjacent angles are supplementary
Given data ,
Let the lines represented by the figure be intersecting lines
And , the missing angle from the first straight line be y
where y = 180° - ( 38° + 90° )
On simplifying , we get
y = 52°
Now , the measure of x is given by
90° + y + x + 10 = 180° ( angles on a straight line )
On simplifying , we get
90 + 52 + 10 + x = 180
Subtracting 152 on both sides , we get
x = 28°
Hence , the measure of angle is x = 28°
