#1**+2 **

For the first one...we need to remember something

Angle SUT intercepts diameter ST.....when we have this situation, the measure of SUT = 90°

So angle TSU = 180 - 90 - 43 = 47°

And we know that

2 measure of TSU = 9x - 14

2 (47) = 9x - 14

94 = 9x - 14 add 14 to both sides

108 = 9x divide both sides by 9

12 = x
