Answer asap if the measure of angle 3 is equal to (2x + 6)° and x = 7, which statements are true? check all that apply. answers: the measure of angle 6 is 20°. the measure of angle 5 is 70°. the measure of angle 2 is 80°. angles 2 and 5 are complementary. angles 5 and 6 are supplementary. angles 1 and 4 are supplementary.

Evaluating the measure of angle 3, you find it to be (2·7+6)° = 20°. Vertical angles are equal; angles created from a right angle are complementary; two right angles add to 180°, so are supplementary. Using these relationships, you can determine the applicable answers to be ...

• The measure of angle 6 is 20°.

• The measure of angle 5 is 70°.

• Angles 1 and 4 are supplementary. (Only because two 90° angles are supplementary. In general, vertical angles are not supplementary.)

The measure of angle is

The measure of angle is

Angles and are supplementary

Step-by-step explanation:

we have that

so

For

Statements

Verify each statement

case A) The measure of angle is

The statement is True    

we know that

------> by vertical angles

we have that

so

case B) The measure of angle is

The statement is True

we know that

------> by complementary angles

Substitute the value of m<6 and solve for m>5

case C) The measure of angle is

The statement is False

we know that

------> by vertical angles

we have that

so

case D) Angles and are complementary

The statement is False

we know that

------> by vertical angles

so

Angles and are vertical angles and its sum is not equal to  

case E) Angles and are supplementary

The statement is False

we know that

------> by complementary angles

so

Angles and are complementary angles

case F) Angles and are supplementary

The statement is True

we know that

------> by vertical angles

------> by supplementary angles

Because

and

so

Angles and are vertical angles and are supplementary angles
