Find the degree measure of each angle in the triangle

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

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
