Answer:
5.66666666667
Step-by-step explanation:
h(6)=-7
Step-by-step explanation:
replace x with 6
-(6) -1
-6 + -1
-7
Use the line. line it up line up the triangle
The two base angles of an isoceles triangle are equal so we can conclude that
2x - 20 = x + 8
Now we just need to solve for x:
2x - 20 + 20 = x + 8 + 20
2x = x + 28
2x - x = x + 28 - x
x = 28
So, angle B = x + 8 which is 28 + 8 = 36°
