Supplementary angles are angles whose son is 180. To supplementary angles are such that one angle is 4° less than three times th
zzz [600]

Answer:

The measures of angle are 46 degrees and 134 degrees.

Step-by-step explanation:

We are given the following in the question:

Let the measure of one the of the supplementary angles be x degrees.

Measure of other angle =

(3x-4)\text{ degrees}

Since, the two angles are supplementary, their sum is 180 degrees.

Thus, we can write and solve the equation:

x + (3x-4) = 180\\4x = 184\\x = 46\\(3x-4) = 134

Thus, the measures of angle are 46 degrees and 134 degrees.

Y= 1/2x + 2 <br> Select points on the graph
Cloud [144]

Step-by-step explanation:

—x intercept, y = 0

y = 1/2 x + 2

0 = 1/2 x + 2

-2 = 1/2 x

-2.2 = x

-4 = x

X intercept = (-4 , 0)

—y intercept, x = 0

y = 1/2 x + 2

y = 1/2 . 0 + 2

y = 0 + 2

y = 2

Y intercept = (0 , 2)

Graph in the picture :)

Find the coordinates of the midpoint of AB given A (2,3) and B (4, -2)
marshall27 [118]

Answer:

(3, 1/2)

Step-by-step explanation:

The x-coordinate of the midpoint of AB is the arithmetic mean of 2 and 4, which comes out to 3.  The y-coordinate of the midpoint of AB is the arithmetic mean of 3 and -2, which comes out to 1/2.

Thus the midpoint of AB is (3, 1/2).
