If the measure of angle 3 is equal to (2x + 6)° and x = 7, which statements are true? check all that apply. 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.

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

see the attached figure to better understand the problem

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

no idea
