x = 80
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
x + 30 + 70 = 180, that is
x + 100 = 180 ( subtract 100 from both sides )
x = 80
Radius = diameter x 0.5
0.5x0.5 = 0.25meter
0.25 meter x 100 cm (100cm in one meter) = 25cm
also for future reference circumference = pie x r squared.
