Answer:
∠EFH
Step-by-step explanation:
If AB and CD are parallel lines and EF is a transversal line, then angles formed on the same side of the transversal line and are exterior to the parallel lines are same side exterior angles.
Same side exterior angles theorem states that same-side exterior angles are supplementary.
From the image attached below:
∠ABC and ∠EFH are same side exterior angles, therefore:
∠ABC + ∠EFH = 180°
Answer:
Part a) The ratio of the perimeters is 
Part b) The ratio of the areas is 
Step-by-step explanation:
Part A) What is the value of the ratio (new to original) of the perimeters?
we know that
If two figures are similar, then the ratio of its perimeters is equal to the scale factor
Let
z-----> the scale factor
x-----> the perimeter of the new triangle
y-----> the perimeter of the original triangle

we have

substitute

Part B) What is the value of the ratio (new to original) of the areas?
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
z-----> the scale factor
x-----> the area of the new triangle
y-----> the area of the original triangle

we have

substitute


Simple interest formula:
Total = principal x (1 + rate x years)
10 years:
Total = 15,000(1+0.04x10)
Total = $21,000
8 years:
Total = 15000(1+0.04x8)
Total = $19,800
Savings = 21,000 - 19,800 = $1,200
Answer:
40x = 2,000
x = 50
Step-by-step explanation:
to find x of the equation 40x you first want to try different number until you get 2000 and in 40x it says you must multiply meaning 40 times a number equals 2000 and 40 times 50 equals 2,000 making x = 50
finding x:
40x - this means to multiply
40/x - this means to divide
40 - x or x - 40: this means to subtract
40 + x or x + 40: this means to add
