The answer is 90 degrees. SO it would be B
Answer:
70 centimeters squared
Step-by-step explanation:
area of trapezoid formula is 1/2 (b1 + b2)
1/2 (7+13)(7)
7 is base 1, 13 is base 2, 7 is the height
1/2(7+13)(7)
1/2(20)(7)
1/2(140)
70
The legs of the triangle are 6.91 feet, 7.9 feet, and 10.5 feet.
<h3>What is a Pythagoras theorem?</h3>
The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
The ratio of the one leg of the right triangle to the other leg of the right triangle must be 8:7.
Let x be one leg and y be another leg. Then we have
x/y = 8/7
y = 7x/8
Then the greatest length of one leg of the right triangle given the other leg of the right triangle is 10.5 feet will be
10.5² = x² + (7x/8)²
110.25 = x² + 49x²/64
110.25 = 113x²/64
x² = 62.44
x = 7.902
x ≅ 7.9 feet
Then the other leg will be
y = 7.9 x 7 / 8
y = 6.91
