Answer:
b = 60
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
b² + 63² = 87²
b² + 3969 = 7569 ( subtract 3969 from both sides )
b² = 3600 ( take the square root of both sides )
b = = 60
Answer
given,
side of rectangle, AB = CD = 32
BC = DA = 24
rectangle is rotated 90° clockwise about C.
then rotated 90° clockwise about D.
Path traveled by the point A for first rotation will be in circle with radius AC.
AC = 40
θ₁ = 90°
D₁ = 1256.64
For the second rotation Point A will move in circular path with radius of AD
AD = 24
θ₁ = 90°
D₂ = 452.39
total path traveled by the point A
D = D₁ + D₂
D = 1256.64 + 452.39
D = 1709.03

Answer:
C (x+2)(2x+3)
Step-by-step explanation:
You can count in the picture that in the top part there are two x's (2x) and three ones (3). So the top would be (2x+3)
On the left side there is one x (x) and two ones (2). It would be (x+2).
So combine them together, it would be (x+2)(2x+3).
C.
