Answer:
x=90 y=45
Step-by-step explanation:
Answer is C
y and 45 are vertical angles
x=90 (right angle)
Answer:
you don't, the fraction 
or 4/5
is already in its simplest form.
Step-by-step explanation:
if you want it as a decimal, simply divide.
numerator by the denominator
4 divided by 5
which is 0.8
Answer:
It is 2 hours, 22 minutes, 48 seconds.
The 2 is obviously 2 hours. For the minutes, .38 * 60 = 22.8, so the minutes is 22. 0.8 * 60 = 48. So 2 hours, 22 minutes and 48 seconds.
Answer:
=60 the second option.
Step-by-step explanation:
Given the trigonometric ratio, we can find the value of the angle by simply finding the inverse of the given ratio.
If for example Cos ∅= a, then ∅=Cos⁻¹a
If Cos (x)= 0.5, then x= Cos⁻¹ 0.5
Cos⁻1 0.5=60°
The angle whose sine is 0.5 is ∅=60°
