The folding chair has different settings that change the angles formed by its parts. suppose measure of angle 2 is 31 and the measure of angle 3 is 72. find the measure of angle 1.

m < 1 = 103 degrees.

Step-by-step explanation:

m < 1 = m < 3 + m < 3.   ( The external angle of a triangle theorem).

So m < 1 = 31 + 72 =  103.

associative property of multiplication

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
