Answer:
m<H = 31 degrees
m< I = 39 degrees
m< J= 110 degrees
Step-by-step explanation:
(x+9) + (2x -5) + (5x) = 180 ....angles inside the interior add up to 180
x+ 9 + 2x -5 + 5x = 180 .... let's simplify
8x + 4 = 180
8x = 180-4
8x= 176
x= 176/8
x= 22
Now let's find the measure of each angle according to what x is:
m<H = (22+9)= 31 degrees
m< I = (2*22-5)= 39 degrees
m< J= (5*22)= 110 degrees
Let's make sure that it equals to 180
31 + 39 + 110= 180
