Answer:
x=180 units
Step-by-step explanation:
C=R
13x+450=15.5 x
15.5x-13 x=450
2.5 x=450
25 x=4500
x=(4500)/25=180
The ratio from the first triangle to the second triangle is 1:2
If it’s a right triangle 1 side is a right angle and if those 2 sides are equal and not right angles then E needs to be a right angle and a right angle is 90 degrees so it’s D
