Answer:
61
Step-by-step explanation:
We see that the triangle is isosceles as the two sides of it are 6.
In an isosceles triangle, you have two sides that are the same and two angles that are the same.
The two congruent angles will be opposite to the congruent sides.
So, we know that both angles must be x.
The Angles of a triangle add up to 180 degrees.
2x + 58 = 180
2x = 122
x = 61 ddegrees
Solution:
We know that:
Sum of interior angles of triangle: 180°We can see that the two lines of the triangle are equivalent.
This means that:
The triangle is an isosceles triangle.The bottom angles must be equivalent.Equation created: 58 + x + x = 180
Simplify the LHS.
58 + x + x = 180=> 58 + 2x = 180Subtract 58 both sides.
=> 58 - 58 + 2x = 180 - 58=> 2x = 122Divide 2 both sides.
2x = 122=> 2x/2 = 122/2=> x = 122/2 = 61Related Questions

what is the equation of the line with y intercept (0.8)and slope 3/5
Answers
Step-by-step explanation:
y = mx + b
m is slope
b is y-intercept
y = 3/5 x + 4/5

Answer:
Yours: mean: 17; median: 17; mode: none
Friends: mean: 16.4; median: 17; mode: 20
You have the higher mean.
Step-by-step explanation:
a.
Your mean:
(18 + 16 + 19 + 15 + 17) / 5
= 17
Your median:
15 , 16, 17, 18, 19
= 17
Your mode:
15 , 16, 17, 18, 19
= No mode (no number comes up repeatly)
Your friend's mean:
(20 + 20 + 13 + 12 + 17) / 5
= 16.4
Your friend's median:
12, 13, 17, 20, 20
= 17
Your friend's mode:
12, 13, 17, 20, 20
= 20

If 2x/2y= 16, what is x-y
Answers
Answer:
15
Step-by-step explanation:
2x/2y = 16
First, we can cancel out the 2s as there is one on the numerator and another on the denominator.
x/y = 16
To make it fraction form, we know that 16 = 16/1.
x/y = 16/1
We then get x and y.
x = 16
y = 1
x - y = 15

Which of the following numbers can be expressed as repeating decimals? 4/7, 2/5, 7/8, 4/9
Answers
Answer:
4/7 & 4/9
Step-by-step explanation:
4/7 <-------- repeating decimal/rational4/9 <-------- repeating decimal/rationalNumbers with a repeating pattern of decimals are rational because when you put them into fractional form, both the numerator a and denominator b become non-fractional whole numbers. ------------------------------- 4/9A repeating decimal is a decimal number that goes on forever. We want to know if the decimal number you get when you divide the fraction 4/9 (4 ÷ 9) is repeating or non-repeating.Here are the steps to determine if 4/9 is a repeating decimal number:1) Find the denominator of 4/9 in its lowest form.The greatest common factor (GCF) of 4 and 9 is 1. Convert 4/9 to its simplest form by dividing the numerator and denominator by its GCF:4 ÷ 1/ 9 ÷ 1 = 4/9Thus, the denominator of 4/9 in its lowest form is 9.2) Find the prime factors of the answer in Step 1.The prime factors of 9 are all the prime numbers that you multiply together to get 9. The prime factors of 9 are:3 x 33) Determine if 4/9 is repeatingA fraction is a repeating decimal if the prime factors of the denominator of the fraction in its lowest form do not only contain 2s and/or 5s or do not have any prime factors at all.

(a+4)^(2)
(a+4)(a+4) = (a^2 + 8a + 16)
(a-1)^(2)
(a-1)(a-1) = (a^2 -2a + 1)

Answers
Answer:
He has 24 motorcycles
Step-by-step explanation:
I hope I could help!
Answer:
36 motorcycles
Step-by-step explanation:
calculate [tex]\frac{3}{5}[/tex] of 80
= [tex]\frac{3}{5}[/tex] × 80 ( cancel 5 and 80 by 5 )
= 3 × 16 = 48
there are 48 motorcycles and buses
let x be the number of buses then 3x is the number of motorcycles , then
x + 3x = 48
4x = 48 ( divide both sides by 4 )
x = 12
number of motorcycles = 3x = 3 × 12 = 36

A car travels at a speed of 65 miles per hour. How far will it travel in 5 hours?
Answers
Answer: Distance = 325 miles
Step-by-step explanation:
Distance = speed*time
We can plug in the values given for time and speed:
Distance = 65 miles/h * 5 hours
Distance = 325 miles
Answer:
325 miles
Step-by-step explanation:
To find out how far the car will travel in 5 hours, we first need to know how far it will travel in one hour.
Well, we are given that information.
Since we know that the car travels 65 miles in 1 hour, we just have to multiply 65 by the number of hours it will drive, which is 5 in this case.
5 x 65 = 325
The car will drive 325 miles in 5 hours.
