Answer:
Step-by-step explanation:
Formula
c^2 = a^2 + b^2
Givens
Hypotenuse (c) = 45
a = 40
b = ?
Solution
45^2 = 40^2 + b^2
2025 = 1600 + b^2 Subtract 1600 from both sides.
2025-1600 = 1600-1600 + b^2 Combine
425 = b^2 Take the square root of both sides.
√425 = √b^2
b = 20.62
Answer
The third side is 20.62 cm

take another screen shot and ask the question again
1.
Since ABCD is a rectangle, then
angleABE = 90 degrees
angle ABE + angle BEA + 41 = 180
Substitute the known and solve for angle BEA
angle BEA + 41 = 90
angle BEA = 49 degrees
But,
x + angleBEA + 61 = 180 (angles in a straight line)
x = 180 - 61 - 49
x = 70 degrees
2.
triangle XYZ is equilateral, meaning all angles in it are the same, each 60 degrees.
Therefore,
Angle YZX = 60
But Angle YZX = x + 32 (exterior angles equal to the sum of the two opposite interior angles)
60 = x + 32
Therefore,
x = 28 degrees
3.
Angle QPR = Angle QRP (equal oppo sides, equal opposite angles)
Therefore, 2angleQRP + 64 = 180 (angle sum of a triangle)
Angle QRP = 58 degrees
But angle QRP = x + 35 (exterior angles equal to the sum of the two opposite interior angles)
58 = x + 35
x = 23 degrees
