Answer:
Angle STR = 78°
Step-by-step explanation:
So, since line QS is a straight line, we know that it's 180°. We also know that angles QTR and STR both add up to 180°. That gives us an equation:
20x + 12 + 10x + 33 = 180
Combine like terms
30x + 45 = 180
Subtract 45 from both sides
30x = 135
Divide both sides by 30
x = 4.5
Now we know the value of x. We just need to plug it into angle STR's given value:
10(4.5) + 33 = angle STR
45 + 33 = angle STR
78° = angle STR

Answer:
x = 34/13
Step-by-step explanation:
3(5x - 6) + 2(x + 8)
15x - 18 = 2x + 16
15x = 2x + 34
13x = 34
x = 34/13
Best of Luck!
Answer:
y=3x+14
Step-by-step explanation:
Well you already know that the slope is 3
parallel lines always have the same slope.
so then you plug in the point (-6,-4) into y=3x+b
-6 is x and -4 is y
-4=3(-6)+b
-4=-18+b
14=b
so your equation is y=3x+14
