Suppose Alex has x dollars
So
Sam has x-2
Answer:
1. 60 cm^2
2. 132.67 cm^2
3. 72.67 cm^2
Step-by-step explanation:
1. Area of rectangle
A = LW = 5 cm * 12 cm = 60 cm^2
2. Area of circle
A = (pi)r^2 = 3.14(6.5 cm)^2 = 132.67 cm^2
3. Area of shaded region
A = area of circle - area of rectangle
A = 132.7 cm^2 - 60 cm^2 = 72.67 cm^2
Answer:
Step-by-step explanation:
step 1
Find the measure of angle C
Remember that the sum of the interior angles of a triangle must be equal to 180 degrees
so
A+B+C=180°
we have
A=57°
B=37°
substitute
57°+37°+C=180°
94°+C=180°
C=180°-94°=86°
step 2
Find the measure of side c
Applying the law of sines
substitute
The dimensions would be x and x+6. The area is 216.
x(x+6) = 216
x^2 + 6x - 216 = 0
(x-12)(x+18) = 0
x = 12---Yes---
x = -18---No, sides cannot be negative---
If one side is 12, the other side is 18. To check:
12 * 18 = 216
216 = 216
Correct
