answer is x = 10 degrees
Step-by-step explanation:
a right angle is 90 degrees. the angles added are 4x + 3x + 2x = 90.
so 9x = 90
divide by 9 on both sides
x = 10
Answer:
The intersection of a solid and a plane is called a cross section of the solid. Describe the shape resulting from a vertical, angled, and horizontal cross section of a cylinder. The cross section is a rectangle.

Answer:
x = - 2 or x = 4
Step-by-step explanation:
To find the x- intercepts let f(x) = 0, that is
(x - 4)(x + 2) = 0
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x + 2 = 0 ⇒ x = - 2
The x- intercepts are at x = - 2, x = 4
