Answer:

A) 55

Step-by-step explanation:

angle 3 is an exterior angle. to find the interior angle of the triangle, subtract angle 3 from 180

180 - 110 = 70

all the angles in a triangle add up to 180.

since angles 1 and 2 are the same, you can call them x.

70 + 2x = 180

70 - 70 + 2x = 180 - 70

2x = 180 - 70

2x = 110

2x/2 = 110/2

x = 110/2

x = 55

Equivalent expression for 6(x+2)
vivado [14]

Answer:

6x+12

Step-by-step explanation:

This is an equivalent expression as all I did was simplify the expression using the distributive property. (6(x)) + (6(2)) = (6x) + (12) = 6x + 12

shown in reverse to prove this is equivalent would look like this. 6x+12 = (6(x)) + (6(2)) = 6(x+2)
