Two angles are supplementary. If one angle measures twice the other, and the number of degrees in the smaller angle.

Svetllana [295]

Answer:

60 Degrees

Step-by-step explanation:

Supplementary means it equals 180 together, so you divide it by 3 because the one is twice as big and you take the smaller answer

$\frac{180}{3} =60$

Is the equation parallel perpendicular or neither ?<br><br> y = 5/4 x+1 and y = 5/4 x-7

weeeeeb [17]

Answer:

Parallel

Step-by-step explanation:

The equation of a line in slope - intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Both given equations are in this form, that is

y = $\frac{5}{4}$ x + 1 → m = $\frac{5}{4}$

y = $\frac{5}{4}$ x - 7 → m = $\frac{5}{4}$

Parallel lines have equal slopes thus the lines are parallel
