Question

PLZ HELP I WILL GIVE THE BRAINIEST!!

Answer 1

Answer:

6.4 ft

Step-by-step explanation:

the sine ratios in every triangle are

a/sin(A) = b/sin(B) = c/sin(C)

here now the names are changed.

j = a = 7 ft

m = b

k = c

J = A = 45 degrees

M = B = 40 degrees

K = C

we are trying to find m (= b) based on these numbers.

m/sin(40) = 7/sin(45)

m = 7 × sin(40)/sin(45) = 6.4 ft
