(Sorry for only partially answering your question)

Answer 2

Answer:

m = 7.32

n = 16.69

O = 64

Step-by-step explanation:

In right angled triangle MNO,

Taking angle M = 26 as a reference angle, we get

Base = 15cm

perpendicular = m

hypotenuse = n

At first, for hypotenuse

cos 26 = base / hypotenuse

cos 26 = 15 / n

n = 15 / cos 26

n = 16.69

Again, for perpendicular

tan 26 = perpendicular / base

tan26 = m/15

m = tan26 x 15

m = 7.32

Now for angle O, we take angle O as the reference angle

So we get,

Hypotenuse = 16.69

Perpendicular = 15

Base = 7.32

Now,

Sin O = perpendicular / hypotenuse

Sin O = 15 / 16.69

O = Sin ^ -1 (15 / 16.69)

O = 64
