study the steps used to solve the equation.
given: - 5 =
choose the property that justifies each step of the
solution.
step 1
- 5
+ 5
= 7
+ 5
step 2:
in onvon
+ 0 = 12
step 1:
step 2:
step 3:
step 4:
step 3:
step 3: = 12
step 4: 2( 3 ) = 12(2)
step 5: c = 24

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

step-by-step explanation:

$452.90 because you needed to round to the nearest cent
