Answer:
Step-by-step explanation:
A(3, - 2), B(1, 5), C(1, - 2)
ΔABC is right angled Δ
AC and BC are legs (cathetus)
= (AC)(BC) ÷ 2 = 
= 7 units²
The ~ symbol means that the 2 shapes are similar, meaning the same shape but not the same size.
To determine the measure of side length EF, you must find the relationship between the 2 side lengths.
You should set these up as ratios of the length to the width. So, for ABCD, it is 30/45. Make this equal to x/75. If you simplify the first ratio to 2:3, you can then multiply by both numerator and denominator by 25 to get x = 25 in/ 75 in.
Another way is to use cross products with you proportion. 75 x 30 = 45x. Solve for x to get 50 inches.
If they are similar, their sides are proportional. Compare 3/5 ratio is the same as x-4/x
The value of the deal should be $40,000.
remember that 5% as a decimal is .05.Let x = value of deal
The equation would be .05x = $2000
Divide both sides by 0.05.
x=40,000
