Answer:
Step-by-step explanation:
3x + -3x - 4y = 8 - 3x
-4y = 8 - 3x
-----------------
-4
y = 8/-4 + 3/4 x
y = -2 + 3/4x

Answer:
H = 120°
Step-by-step explanation:
The sum of the internal angles of a polygon with n sides is given by the formula:
S = (n-2)*180
So, for a pentagon, we have n = 5, then:
S = (5-2)*180 = 540°
So we have that:
M + A + T + H + S = 540° (eq1)
M = T = H (eq2)
A + S = 180° (eq3)
Using the second and third equation in the first one, we have:
H + H + H + 180 = 540
3H = 360
H = 120°
