Anyone know 1 and 2 with work shown please! ^^

1. m∠R = 10

2. m∠P = 160

Step-by-step explanation:

The lines at the opposite are congruent so the angles have to be the same.

6x - 12 = 3x -1

subtract 3x from both sides

3x - 12 = -1

add 12 to both sides

3x = 11

divide by 3

x = 11/3

Now replace x in both the equations with 11/3:

3x - 1 = 3(11/3) - 1 = 11 - 1 = 10

6x - 12 = 6(11/3) - 12 = 66/3 - 12 = 22 - 12 = 10

So m∠R is 10

Now to find m∠P,

A triangle is 180 degrees so with angle P represented with x:

10 + 10 + x = 180

20 + x = 180

x = 160

m∠P = 160

16

step-by-step explanation:

2 x 40 = 80

80/5

= 16
