Answer:
Step-by-step explanation:
Given:
Right ∆ with,
Hypotenuse = x
Opposite = 9
Reference angle 
= 39°.
Required:
The value of x
Solution:
Since we are given a reference angle with opposite length, and we are to find the hypotenuse length, x, apply the following trigonometric ratios formula:
Plug in the values into the equation
Multiply both sides by x
Divide both sides by sin(39)
(to 2 decimal places)
Hi I am learning this too. Okay so first is there any type of picture that shows if angles ABC are congruent to angles CDA. If there is i'll be able to help you.
That's a quadratic equation in
, which means we get an extra square root and
at the end.
We factor,
Answer:
x= -3
Step-by-step explanation:
because i got it right before :)
EF = 6
EG = 21
You would subtract EF from EG to find FG:
21 - 6 = 15.
The answer is B.) 15
