11. Find mZJHI.

Step-by-step explanation:

we have 2 equations that we can set equal to 90. that way, we can find x and then solve the equations for themselves. angle JHI is equal to GJK, which is an angle we can easily find. here is my work:

(3x + 2) + (12x - 17) = 90

15x - 15 = 90

      + 15  + 15

15x = 105

x = 7

3(7) + 2

21 + 2

GJK = 23

so, since the two angles are congruent, that means that angle JHI = 23 degrees

a - base

b - exponent

so,
