To find the value of x, we can set up the equation:

3x + 15 + 60 = 180

Combine like terms:

3x + 75 = 180

Subtract 75 from both sides:

3x = 105

Divide by 3:

x = 35

Therefore, the value of x is 35. So the answer is D) 35.
Make sure to complete ALL Parts - A, B, and C and show ALL of your work for full credit.

Part A: Create an equation and solve for x. Remember that supplementary angles add up to 180 degrees.

x =


Part B: We know that one of the angles is 149 degrees. Use your answer above to find the missing angle measurement.

Missing Angle Measurement =
degrees.
Part A:

We can set up the equation for supplementary angles:

3x + 15 + 60 = 180

Combine like terms:

3x + 75 = 180

Subtract 75 from both sides:

3x = 105

Divide by 3:

x = 35

Therefore, the value of x is 35.

Part B:

One angle is 149 degrees.

The missing angle measurement (which is 3x + 15) is:

3(35) + 15 = 105 + 15 = 120 degrees

Therefore, the missing angle measurement is 120 degrees.
nope try again
Part A:

We know that the two angles are supplementary, meaning they add up to 180 degrees. So we set up an equation:

3x + 15 + 60 = 180

Combine like terms:

3x + 75 = 180

Subtract 75 from both sides:

3x = 105

Divide by 3:

x = 35

So, x = 35.

Part B:

Let's find the missing angle by substituting x back into the expression for the missing angle:

Missing angle measurement = 3(35) + 15 = 105 + 15 = 120 degrees

Therefore, the missing angle measurement is 120 degrees.
THAT ISNT THE ANSWER. TRY. AGAIN.
Apologies for the oversight.

Part A:

We know that the two angles are supplementary. Therefore, the sum of the two angles is 180 degrees:

3x + 15 + 60 = 180

Combine like terms:

3x + 75 = 180

Subtract 75 from both sides:

3x = 105

Divide by 3:

x = 35

Therefore, the value of x is 35.

Part B:

Given that one of the angles is 149 degrees, we can find the missing angle by substituting x back into 3x + 15:

3(35) + 15 = 105 + 15 = 120

Therefore, the missing angle measurement is 120 degrees.
