Step-by-step explanation:
If you don't have these memorized yet, your calculator can help you with this.
Complementary angles are those angles whose sum is 90 degree.
The measurement of two complementary angles are

There sum have to be 90 degree. That is

Combining like terms ,

Moving 20 to right side

Dividing both sides by 5

So the measurement of the angles are

It is 5/4 yards, you just add
When the denominator ( the bottom number ) is the same, just add the numerator ( the top number ) together :)
hope this help
Step-by-step explanation:
with reference angle E
perpendicular (p) = e
base(b) = g
hypotenuse (h) = f
so Now
Sin E
= p/h
= e/f
W=0.9
So w = 0.9 and v = -4
