Answer:

a) w = 17.8 m

b) b = 7.5 mm

c) a = 6.6 mm

d) a = 10.3 mm

Explanation:

a)

a^2 + b^2 = c^2

w^2 = 13^2 + 12.2^2

w^2 = 169 + 148.84

w = square root (317.84)

w = 17.8 m

b) 6.1^2 + b^2 = 9.7^2

b^2 = 94.04 - 37.21

b^2 = 56.83

b = 7.5 mm

c) a^2 + 3.5^2 =7.5^2
a^2 = 56.25 - 12.25

a = square root 44

a = 6.6 mm

d) a^2 + 9.5^2 = 14^2
a^2 = 196 - 90.25

a = square root 105.75

a = 10.3 mm
