Find the length of the missing sides Write your answer in si

Find the length of the missing sides. Write your answer in simplest radical form.

Solution:

1. since It is an right angled triangle

therefore

tan(45) = height / base

1 = x/7

x =7

cos(45) = base/ hypotenous

1/root2 = 7 /y

y = 72

(22) angle is not visible

23. since trinagle is right

cos(60) = base/ hypotenuse

1/2 = x/4

x = 2

sin(60) = y/4

3/2 =y/4

y= 23

(24) value of side is not visible
