Answer:
35°
Step-by-step explanation:
The base angles of an isosceles triangle are congruent , then
base angles =
=
= 35°
B. 6
Explanation: 8(6+4)= 80
38+ 7(6)= 80
Answer:
x = 36
Step-by-step explanation:
<em>A triangle has 180°</em>.
That <em>third angle is 360 - 8x</em>.
So the equation is: <em>180 = 2x + x + 360 - 8x</em>.
Simplify: 180 = -5x + 360
Add/Subtract: 5x = 180
Divide: x = 36.
I think it’s 5 I’m not really for sure
