Answer:
A) x = 12
B) = 154
Explanation:
RVT is a straight line so it must have an angle of 180º. If we take the 26º from ST we know that RS is equal to 154º
So we should set the equation (15x-26) = 154
We should always keep the equation balanced so to do this we're going to add 26 to both sides to get x by itself.
Your equation should now look like this. 15x = 180
Then divide both sides by 15 to get x = 12
We know that UR is also 26º because RS is 154º That makes RU congruent to ST and RS congruent to UT
