Answer:

See explanation

Explanation:

1st photo:

(a) MKL ~ MLJ ~ LKJ

basically, you have to match the corners to each other (i dont have a better way of explaining this sorry)

(b) KL/KJ = KM/LK AND LJ/MJ = KJ/JL

match sides to each other

2nd photo:

(a) d = 7
√(2)

you have to use special right triangle rules for a 45-45-90 triangle

(b) a =
(4√(3) )/(3)

you have to use special right triangle rules for a 30-60-90 triangle

3rd photo:

x = 38.9°


cos^(-1)(7/9) = 38.9°
