M1= (x+42)° and m/2=3xº.

angle 1= 54

angle 2= 36

Step-by-step explanation:

We know that's a right angle because it has a square in the corner instead of a circle, so the overall measure is 90.

we can set up the equation like this: m1+m2=90

(x+42)+3x=90

calculate it and you'll get x

x=12

put 12 into the angle equations

1: 12+42=54

2: 3(12)=36

Step-by-step explanation:

4(2x+3)-5y

=8x+12-5y

Sum means addition: 2x+3

Term: Term could be a single number , variable, or the product of both. we have 8x, 12,-5y

Product ( multiplication): we have 4(2x+3), 2 multiplied by x(2x), 5y

Factor(part of a product : factor of 8x=8, x, 2 and 4

Factor of -5y=-5 and y

Factor of 12=2,4,6

Quotient ( it is the result obtained by dividing one quantity by another)= Not present in the expression. The expression doesn't have a division

Coefficient : is a number which is in product with variable.

Coefficient of 8x=8

Coefficient of -5y=-5

Coefficient of 12=12
