Answer:
H^2 = P^2+ B^2
10^2 = 3x^2 +4x^2
100 = 9x^2 + 16x^2
100 = 25x^2
100 ÷ 25 = x^2
4 = x^2
x= 2
Length of longer arm is 4x = 4×2=8

Answer:
r=7
Step-by-step explanation:
6r-7+90+55=180
6r+138=180 ----- 6r=180-138
6r=42 ----- divide both sides by 6
r=7
(We get the 90 from the 90degrees in the middle of this supplementary angle and the total, 180, from the straight angle made from all three angles.)
