7 0

Answer:

x≈ -4.71

Step-by-step explanation:

7(x+6)=9

Distribute the 7 into the parenthesis.

7x+ 7(6)= 9

Multiply the numbers.

7x+ 42= 9

Subtract from both sides.

7x+42= 9

    -42  -42

Now, divide to both sides.

<u> 7x</u>= <u>-33</u>

7       7

x= -4.71428571429

x≈ -4.71

Which of thw following are remote interior angles of &lt;1 check all that apply
atroni [7]
Hi there!

A remote interior angle is an angle that is located inside a triangle and at the opposite side of another angle. Therefore, every exterior angle has two remote interior angles.

The question asks for the remote interior angles of <1. First we must realise that the angle we're looking for is located inside the triangle. Our possibilities are <3, <4 and <5. Moreover, the angle must be at the opposite side of the exterior angle, and thus <5 isn't a remote interior angle.

The two remote interior angles of <1 are <3 and <4.
