What is the value of x?

Step-by-step explanation:

With reference angle 60°

perpendicular (p) = 2√3

hypotenuse (h) = ?

We know

sin 60° = p/h

√3/2 = 2√3 / h

cross multiply

h =( 2√3 * 2)/ √3

therefore h = 4

So

Now

with reference angle 45°

perpendicular (p) = x

base (b) = 4

Now

tan 45° = p/b

1 = x / 4

Therefore x = 4

Hope it will help you :)

x = 20

Step-by-step explanation:

The ratios of corresponding sides are equal, that is

= , substitute values

= ( cross- multiply )

20(25 + x) = 900 ( divide both sides by 20 )

25 + x = 45 ( subtract 25 from both sides )

x = 20
