Answer:
∠RQS=72 ∠SQT=83
Step-by-step explanation:
4x-20+3x+14=155
7x-6=155
7x=161
x=23
∠RQS=23*4-20=92-20=72
∠SQT=155-72=83
Answer:
a) 67 inches (y-intercept)
b) Vertex form y=(x+8)^2+3
c) Difference is 64 inches (vertex minus y intercept)
2arctan(2/5) = 44°
180° -44° = 136°
The angles are 44°, 136°.
