All 3 angles of a triangle must equal to 180. You can simply set up an equation to solve this and set it equal to 180.
Angle 1 - 50 + x
Angle 2 - x
Angle 3 - 2x -10
50+x+x+2x-10=180
4x+40=180
4x=140
x=35
Angle 1 = 50+35= 85
Angle 2 = 35
Angle 3 = 2(35) - 10 = 60
60+35+85=180
Answer:
The change in X=1 Y=-4
Step-by-step explanation:
-2 + 1 = -1
9 - 4 = 5
Answer:
2. -3/4
Step-by-step explanation:
slope formula is y2-y1/x2-x1
-1-8/10-(-2)
simplify the two negatives make a positive
-9/12
simplify
-3/4
X=10 and y=5 so it's the first option
Answer:
45
Step-by-step explanation:
Multiply 75 by 0.6:
75(0.6)
= 45
