The answer is A because angle 7 and angle 3 are corresponding angles :)
Answer:
Step-by-step explanation:
<u>Area of the square is 9 in², so side of the square is:</u>
<u>The diagonal of the square is the diameter of the circle.</u>
<u>Circumference of circle:</u>
<u>Area of circle:</u>
<u>Ratio of circumference to area:</u>
- C/A = 3√2π / (9/2π) = 2√2/3
<span>The side of one square is 2 cm longer than the side of a second square.
If the combined area of the squares is 100 square cm, find the dimensions
of each square.
:
The area of the two squares
x^2 + (x+2)^2 = 100
x^2 + x^2 + 4x + 4 = 100
2x^2 + 4x + 4 - 100 = 0
2x^2 + 4x - 96 = 0
Simplify, divide by 2
x^2 + 2x - 48 = 0
Factors to
(x+8)(x-6) = 0
the positive solution
x = 6
:
6 by 6 the small square
8 by 8 the large square

Check: 36 + 64 = 100 Does this make sense to you?</span>
4.29*1015=4354.35
1.77*10^-4= 0.000177
first * second = 0.77071995 with your own sig figs
