Answer:
A ≈ 117.3 cm²
Step-by-step explanation:
Pythagorean Theorem: a² + b² = c²
Area of a Triangle: A = 1/2bh
If Triangle A ≅ Triangle B, then the bottom side length of A would be 11 cm and the hypotenuse will stay 24 cm.
Step 1: Find the vertical leg of A
11² + b² = 24²
121 + b² = 576
b² = 455
b = 21.3307 cm
Step 2: Find area of A
A = 1/2(11)(21.3307)
A = 1/2(234.638)
A = 117.319
A ≈ 117.3 cm²
Finding x.
Suzette ran = x
Suzette biked = 4x
7 = x + 4x --) 7 = 5x --) 1.4 = x
Suzette ran for 1.4 hours
Finding y.
Quickest way is to use Suzette biked = 4x and substitute the x for 1.4 to find how much she biked.
4 x 1.4 = 5.6
1.4 + 5.6 = 7 hours the total time exercising
And the mileage adds up to.
5(1.4) + 20(5.6) = 119
6/16 I BELIVE but i am not too sure
B they only have one pair of parallel sides. The top and bottom
