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

Step-by-step explanation:
Answer:
See below.
Step-by-step explanation:
5a)
In an isosceles triangle, the angles opposite the congruent sides are congruent.
m<A = 40 deg
m<B = 40 deg
m<A + m<B + m<C = 180
40 + 40 + m<C = 180
m<C = 100 deg
5b)
In a right triangle, one angle is a right angle.
m<A = 40 deg
m<B = 90 deg
m<A + m<B + m<C = 180
40 + 90 + m<C = 180
m<C = 50 deg
