In AHIJ, m angle H=(x-1)^ ,m angle I=(2x+5)^ , and m angle J=(7x+6)^ . What is the value of ?

A=73

B=17

Step-by-step explanation:

From above, you can see that A+B=90

So I can add my two angles together and have it equal to 90

( 5 x + 8 ) + ( x + 4 ) = 90

5 x + 8 + x + 4=90

6 x + 12 = 90

6 x = 90 − 12

6 x = 78  

x = 13  

So  A = 5 x + 8=5 ( 13 ) + 8 = 65 + 8 = 73  

and  B = x + 4 = 13 + 4 = 17

Just to make sure you are correct, add your A and B together and they should equal to 90  

A + B = 73 + 17 = 90

Hope This Helps You :)
