Answer:
x = 85
Step-by-step explanation:
Formula
a^2 + b^2 = c^2
Givens
Solution
- 13^2 + 84^2 = x^2 Substitute the givens into the formula
- 169 + 7056 = x^2 Add the left
- 7225 = x^2 Take the square root of both sides.
- sqrt(7225) = sqrt(x^2)
- x = 85
A² + b² = c²
a = 2b, c = 10
(2b)² + b² = 10²
4b² + b² =100
5b² = 100
b² = 100 ÷ 5
b² = 20
Answer: 20
Answer:
Step-by-step explanation:
Based on the rules of rotation, when the original point (x,y) is rotated according to the following degrees and direction, it will have the corresponding ending points.
90 degrees counterclockwise (-y, x)
90 degrees clockwise (y, -x)
180 degrees counterclockwise and clockwise (-x,-y)
In this case, it would be a 90 degrees clockwise rotation because (x,y) becomes (y,-x)
and there is a translation of 1 unit to the left.
