Answer:
∡S corresponds to ∡X
∡TXY = ∡RST
∡XTY = ∡SRT
∡XYT = ∡STR
Step-by-step explanation:
You want to do to one side the same thing you do to the other side.
In order to get the n by itself you divide the 25n by 25. But in order to not change the answer you need to do the same to the 70.

so n=

which can be reduced to

so n=

Answer:
21°
Step-by-step explanation:
we know that every single triangle has to equal 180°
we have all 3 angles 90° 34° 35° which equal 159°
so we take 180°-159° and your answer is 21°
14 = 31.7 - 3x
-17.7 = -3x
x = 5.9
