Its 28 degrees. the equation is 28x+40+7x=180

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.

Need help i dont understand this.
inn [45]
The range is a statistical property that consists of the difference between the biggest and the smallest given number.

In our case, the biggest is 17.3 million and the smallest is 3.3 million:

17.3 - 3.3 = 14.0


The range is 14.0 million acres (option D, 4th option).


Hope it helped,

Happy homework/ study/ exam!
