Answer:
18
Step-by-step explanation:
Answer:
3x+2x+a=180 degree(being linear pair)
5x+25=180
5x=180-25
x=155/5
x=31
Step-by-step explanation:
Answer:
H= 2A over b(1+b)
Step-by-step explanation:
Answer:
2.2 m
Step-by-step explanation:
Assuming that spoke refers to the radius (r) of the wheel, you can determine the circumference of the wheel using 2(pi)(r).
2 x (22/7) x 35cm
= 220cm
As this answer is in cm, it needs to be converted to m to be a correct answer. As 1m = 100cm, 220cm x 0.01 = 2.2m
