Triangle abc is a right triangle. find the measure of side b. round to the nearest hundredth. a) 6.13 cm b) 6.71 cm c) 9.53 cm d) 10.54 cm e) 12.45 cm

C)9.53 cm

Step-by-step explanation:

We know this is a right triangle, so we can use trig relations

tan A = opposite side/ adjacent side

tan 40 = 8/b

Multiply each side by b

b tan 40 = 8

Divide each side by tan 40

b tan 40 / tan 40 = 8 / tan 40

b = 8/ tan 40

b = 9.534028741

x+y = 29, 5x + 2y = 100

step-by-step explanation:

i'm guessing it was a multiple first option was the correct answer
