I’m asking again bc I really need a answer ;_; If the measure of angle 6 is 123 degrees, what is the measure of angle 1?

57 because 6 is 123 and so is 4 so 180 - 123 and you get 57.

The measure of angle one is 57.

Step-by-step explanation:

The 2 angles are supplementary, which means that they add up to 180 degrees.

180-123=57

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
