Answer:
540°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 5, hence
sum = 180° × 3 = 540°
40000+1000x=60000
-40000. -40000
1000x=20000
x=20
Answer:
c = 5
Step-by-step explanation:
a^2 + b^2 = c^2
3^2 + 4^2 = c^2
9 + 16 = 25
c^2 = 25
sqrt of 25 = 5
c= 5
Answer:
x=55
Step-by-step explanation:
The 3 angles of a triangle add up to 180 degrees
<A + < B + <C = 180
x + 75+ 50 = 180
x + 125 = 180
subtract 125 from each side
x = 180-125
x = 55
