Can someone help and can you also put the reason why it is the answer?

5 c = 45 , d = 97

Step-by-step explanation:

5) You know the entire triangle has a total of 180 degrees, you also know that angle c + 135 has to equal 180.

So for angle C, you will set up your formula c=180-135 = 45

Now you set up your formula for angle d.

180=angle c + angle d +38

180 = 45 + D + 38 -> D = 180-45-38 = 97

Follow the same steps for 6 and 7

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
