Step-by-step explanation:
You want to isolate the variable first. Then solves the rest. I hope this helps! Please mark me brainliest. I just need one more!
Answer:
x = 40.8°
Step-by-step explanation:
Since the triangle is right use the tangent ratio to solve for x
tanx° = 
= 
x = 
() ≈ 40.8°
Answer:
1 to 2 is an example inches to 2 stuck etc
The initial statement is: QS = SU (1)
QR = TU (2)
We have to probe that: RS = ST
Take the expression (1): QS = SU
We multiply both sides by R (QS)R = (SU)R
But (QS)R = S(QR) Then: S(QR) = (SU)R (3)
From the expression (2): QR = TU. Then, substituting it in to expression (3):
S(TU) = (SU)R (4)
But S(TU) = (ST)U and (SU)R = (RS)U
Then, the expression (4) can be re-written as:
(ST)U = (RS)U
Eliminating U from both sides you have: (ST) = (RS) The proof is done.
