To determine the value of angle r, we need additional information or context. Please provide more details.
Two adjacent angles have a sum of 100°. The angles have measures ∠1 = 20° and ∠2 = (3x + 15)°. What equation can be used to solve for x?(1 point)
Responses
3x+115=20
3 x plus 115 is equal to 20
3x−20=100
3 x minus 20 is equal to 100
3x−100=20
3 x minus 100 is equal to 20
3x+35=100
The equation that can be used to solve for x is 3x + 15 + 20 = 100.
So, the correct equation is 3x + 35 = 100.
