Answer:
20
Step-by-step explanation:
4^2= 16
16+7=23
23-3=20
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°
Answer:
True
the answer to the above question is true
Answer:
x = 3b/2 + 3y/2
Step-by-step explanation:
Goal: Find x
To do that we must isolate x on one side of the equation.
2/3x - y = b
2/3x - y + y = b + y
2/3x = b + y
2/3x ÷ 2/3 = b + y ÷ 2/3
(When we divide fractions we multiply by its reciprocol.)
x = 3b/2 + 3y/2
