Answer:
1. x = 20
2. x = 3
3. RST = 22 degrees
Step-by-step explanation:
1. Since QR bisects PQS, the measure of the angles PQR and PQS should be equal, so we can set their expressions equal to each other, and then solve.
4x-10 = -3x+130
4x = -3x +140
7x = 140
x = 20
2. Since there is a CAB has a right angle, the measure of angles CAD and BAD should add up to 90 degrees. So we can set the sum of their expressions equal to 90 degrees.
(5x+57) + (x+15) = 90
6x + 72 = 90
6x = 18
x = 3
3. I can't see where the R is but if it is on the empty line then we can find RST by subtracting the measure of angle TSU from angle RSU.
TSU - RSU = RST
91 - 69 = 22 degrees
RST = 22 degrees
Answer:
x < -12
Step-by-step explanation:
−21x>6
Multiply both sides by -2(−2)2−1x>(−2)6
Simplify - remember to flip the inequality symbolx<−12
