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!
