Answer:
- Question 1: x=55
- Question 2: m∠A=45°
Step-by-step explanation:
Question #1
- Since it is an isosceles triangle, this means that the base angles have the same value.
- The angle sum is 180°
Solve
2x+35+35=180
2x+70=180
2x=110
x=55
Question #2
- Since it is given there is a right angle, this means the angle is 90°
- The angle sum is 180°
Solve
5x+5x+90=180
10x+90=180
10x=90
x=9
It asked to find m∠A, which is 5x. So 5x=5(9)=45°
Hope this helps!! :)
