Answer:
5 and 85 degrees
Step-by-step explanation:
Ok, so if 2 angles are complementary, that means when put together they equal 90 degrees.
So, let's say one angle is a.
This means the bigger angle would be 17 times the smaller angle, or 17a.
Now let's make an equation:
a + 17a = 90
Now, we have to combine the like terms:
18a = 90
Now in order to find the smaller angle, we just have to divide by 5:
a = 5
This means that the smaller angle is 5 degrees, but because the bigger angle is 17 times the size, we just multiply 5 and 17 together to get 85 degrees.
Hope this helps :)

Answer:
x = 1
Step-by-step explanation:
2x + 8 = 4x + 6
<em>subtract 6 from both sides of the equation</em>
2x + 8 - 6 = 4x + 6 - 6
2x + 2 = 4x
<em>subtract 2x from both sides of the equation</em>
2x - 2x + 2 = 4x - 2x
2 = 4x - 2x
2 = 2x
<em>divide both sides of the equation by 2</em>
2/2 = 2x/2
1 = x
Answer:
the ball reaches a height of 64 feet after 2 sec.
The ball is in the air 4 sec.
Step-by-step explanation:
The ball is following the path of a parabola. The maximum height is at the vertex of the parabola.
Let (h, k) be the vertex. h will be the time it takes to reach the maximum height, and k will be that height.
y =
h = -b/2a = 64/(-2)(-16) = 64/32 = 2
k = -16(2)^2 + 64(2)
-16(4) + 128
- 64 + 128 = 64
V: (2, 64)
So the ball reaches a height of 64 feet after 2 sec.
Let = 0 (0 is the height when the balls hits the ground)
-16t(t - 4) = 0
t = 0 or t = 4
The ball is in the air 4 sec.
