Answer:
y =65
Step-by-step explanation:
We will call the unknown angle in the triangle x
Angle x plus 130 form a straight line
x+130 = 180
Subtract 130 from each side
x+130-130 = 180-130
x = 50
The three angles in the triangle add together to make 180 degrees
x+y+y = 180
We know angle x = 50
50 + 2y = 180
Subtract 50 from each side
50+2y-50 = 180-50
2y = 130
Divide each side by 2
2y/2 = 130/2
y = 65
7 / 8 = 0.875
It is a terminating decimal because the decimal has a finite amount of numbers.
Answer:
Triangle E
Step-by-step explanation:
(x,y) --> (y,-x)
Answer:
195 minutes
Step-by-step explanation:
3 x 60 = 180
.5 x 60 = 30
.5 x 30 = 15
.25 x 60 = 15
180 + 15 = 195
