Answer:

B. 33

Explanation:

Since we know what m<2 and m<3 is we can put it into an equation.

Since m<2 is x+8 and m<3 is 2x+7 we can put it into an equation:

x+8+2x+7

Since we already know the angle for the bottom right corner (90˚) we can add it to the equation:

x+8+2x+7+90=180

Since 180 is always the total for triangle

Now we just solve for "x"

3x+15+90=180

3x+105=180

3x=75

x=25

Now we can substiute x with 25

instead of x+8 it is 25+8 which is 33

So the answer is B. 33

Hope this helps!
