Answer:
a = 50°, b = 130°, c = 20°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles in the right triangle
a + 40° + 90° = 180°
a + 130° = 180° ( subtract 130° from both sides )
a = 50°
a and b are adjacent angles and sum to 180° , so
a + b = 180°
50° + b = 180° ( subtract 50° from both sides )
b = 130°
Then sum the angles in the top triangle, that is
30° + 130° + c = 180°
160° + c = 180° ( subtract 160° from both sides )
c = 20°
Answer:
y=mx+b where m is slope and b is y int
Step-by-step explanation:
1) slope 1/4 and yint 8
2) slope -2 and yint -3
3)slope 0 and y -int is 0 when there is no b
4) Slope is 0 and y int is 7 when there is no B
Answer:
Step-by-step explanation:
1.5x - 15 dollars = x - 20 Add 15 to both sides.
1.5x - 15 + 15 = x - 20 + 15
1.5x = x - 5 They will never coincide.
1.5x-x = - 5
0.5x = - 5 Multiply by 2
x = - 10
