Question

In AHIJ, m_H=(8x-6)°, m_1=(2x-4)', and m2)=(x-8)". Find mcH.

Answer 1

9514 1404 393

Answer:

m∠H = 138°

Explanation:

Perhaps you have ΔHIJ and want the measure of ∠H.

∠H +∠I +∠J = 180°

(8x-6) +(2x-4) +(x-8) = 180

11x -18 = 180 . . . . . . collect terms

11x = 198 . . . . . . . . . add 18

x = 18 . . . . . . . . . . . divide by 11

Then angle H is ...

m∠H = (8(18) -6)°

m∠H = 138°
