N76 [4]3 years ago
5 0

Answer:

-2

Step-by-step explanation:

The equation of the line is written in y=mx+c form, where m is the gradient and c is the y-intercept.

In this case, your m is a -2 and your c is a -3.

Hence the gradient of the line is -2.

An angle measures 74° less than the measure of its supplementary angle. What is the measure of each angle?
Olin [163]

Given that the two angles are supplementary, the measure of each angle is 127° and 53°.

<h3>What is the measure of each angle?</h3>

Supplementary angles are two angles whose sum is 180 degrees.

Given the data in the question, let 'x' represent the measure of the first angle.

  • Measure of first angle = x
  • Measure of second angle = x - 74
  • Sum of the complementary angles = 180°

Since supplementary angles are two angles whose sum is 180 degrees.

Measure of first angle + Measure of second angle = 180

x + ( x - 74 ) = 180

x + x - 74 = 180

2x - 74 = 180

2x = 180 + 74

2x = 254

x = 254/2

x = 127°

Hence,

Measure of first angle = x = 127°

Measure of second angle = x - 74 = 127 - 74 = 53°

Given that the two angles are supplementary, the measure of each angle is 127° and 53°.

Step-by-step explanation:

The opposite angles in a cyclic quadrilateral are supplementary. The sum of the opposite angles is equal to 180˚

x+100=180

x=180-100=80
