The answer is 5 because if you add 10 to -10 it is 0 then add the 5 more and it is 5.
What you need to know for this case is that the sum of the internal angles of a triangle is 180 °
We then have the following equation that is given by:
(2x) + (3x) + (4x) = 180
Clearing x we have:
9x = 180
x = 180/9
x = 20
Therefore we have:
m∠A = (40) °
m∠B = (60) °
m∠C = (80) °
Answer:
B) m∠B = 60 °
90x+60y=72
60y=-90x+72
y=-1.5x+1.2
then create a graph using this formula.
Hope this helps!
