Question

There are two complementary angles, ∠5 and ∠6 . If m∠5=39° , what equation can you write to solve for m∠6 ?(1 point)
Responses

m∠6=180°−39°
x equals 180 degrees minus 39 degrees

m∠6=39°
x equals 39 degrees

m∠6+39°=180°
x plus 39 degrees equals 180 degrees

m∠6+39°=90°
x plus 39 degrees equals 90 degrees

x°+77°=180°
x plus 77 degrees equals 180 degrees

x°=77°
x equals 77 degrees

x°=90°−77°
x equals 90 degrees minus 77 degrees

x°+77°=90°
x plus 77 degrees equals 90 degrees

The correct equation to solve for m∠6 is:

m∠6=180°−39°

I apologize for the confusion. You are correct. The correct equation to solve for m∠6 is:

m∠6=180°−39°

This is because the two angles are complementary, which means their measures add up to 90 degrees. Therefore, if one angle is 39 degrees, the other angle can be found by subtracting 39 degrees from 90 degrees.

The correct equation to solve for m∠2 is:

x°+77°=180°

This is because the two angles are supplementary, which means their measures add up to 180 degrees. Therefore, if one angle is 77 degrees, the other angle can be found by subtracting 77 degrees from 180 degrees.

To find the measure of ∠B, we can set up an equation using the fact that the measures of all three angles add up to 180 degrees.

m∠A + m∠B + m∠C = 180°

Substituting the given measures:

67° + (2x+20)° + x° = 180°

Combine like terms:

67° + 2x + 20° + x = 180°

Combine like terms again:

3x + 87° = 180°

Subtract 87° from both sides:

3x = 93°

Divide both sides by 3:

x = 31°

Now we can substitute this value back into the expression for ∠B:

m∠B = 2x + 20° = 2(31°) + 20° = 62° + 20° = 82°

Therefore, the measure of ∠B is 82 degrees.
