Its 28 degrees. the equation is 28x+40+7x=180
after u figure that out you should get x=4 but its 7x so you do 7×4 which is 28

Two angles are supplementary if their sum is 180 degrees.

Here we are given:

Angle GHI measures (28x + 40)° and angle JHI measures (7x)°.

Sum of angle GHI and JHI is 180.

$angle GHI + angle JHI = 180$

$(28x + 40) + (7x) = 180$

$35x = 140$

dividing both sides by 35,

x=4

Now let us find angle JHI

angle JHI = 7x = 7*4 =28

Answer : Angle JHI is 28 degrees.
