The value of m ∠ RPS is 64. 7°

<h3>What are collinear angles?</h3>

Collinear angles are angles formed when three or more points lie on the same straight line.

Note that angles on a straight line sum up to 180 degrees.

From the diagram given, we can see that the angles are collinear angles and thus sum up to 180 degrees;

  • m ∠QPS = 88°
  • m ∠ RPS = 5x + 34°
  • m ∠ QPR = 8x + 15°

m ∠QPS + m ∠ RPS + m ∠ QPR = 180°

88° + 5x + 34° + 8x + 15° = 180

collect like terms

5x + 8x = 180 - 137

Add like terms

13x = 43

Make 'x' the subject of formula

x = 43/ 7

x = 6. 14

m ∠ RPS = 5x + 34 = 5 ( 6. 14) + 34 = 30. 7 + 34 = 64. 7°

Thus, the value of m ∠ RPS is 64. 7°

Where did we get one?
77julia77 [94]

Answer:

The -1 came from factoring.

The equation is multiplied by 8 because 8 could be pulled from 16x-8.

16 can be divided by 8 2 times and 8 can only divided by 8 once.

so factoring it makes the equation 8(2x-1)
