<h3>
Answer: x = 45</h3>
Work Shown:
x+x+90 = 180 .... all three angles of a triangle add to 180
2x+90 = 180
2x = 180-90
2x = 90
x = 90/2
x = 45
This is a 45-45-90 right triangle. We also consider it an isosceles right triangle because the base angles (45) are equal.
Answer:

Step-by-step explanation:
First find difference between the divisors and remainders.

Here, the difference between the divisors and remainders is equal.
So, the required number is equal to LCM of 

LCM of 
Required Number 
Answer:
The scale factor is the ratio of the length of a side of one figure to the length of the corresponding side of the other figure.
Step-by-step explanation:
Those are alternate interior angles and are equal. B.5x=80 x=16.
