These 2 angles are "vertical angles." Thus, angle 1 = angle 4.
Therefore, 6x+1 = 8x-17. Solving for x, 2x = 18 and x = 9 (answer)
Answer:
no
Step-by-step explanation:
y = 3x
Substitute the point into the equation
2 = 3*0
2 =0
This is not true so the point is not a solution
V=hpir^2
I will assume that the first one is the one with radius 16 and height 40
2nd is radius 7 and height 26
1. v=hpir^2
v=40pi16^2
v=40pi256
v=10240pi cubic inches
3rd option
2.
v=hpir^2
v=26(3.14)7^2
v=26(3.14)(49)
v=1274(3.14)
v=4000.36 cubic cm

Answer: x = 19.7 (choice C)</h3>
=========================================================
Explanation:
The reference angle is 24 degrees. Opposite that angle is the side 8 units long. The horizontal portion is unknown and it's the adjacent side.
Also unknown is the value of x which is the hypotenuse.
To summarize:
- opposite = vertical leg = 8
- adjacent = horizontal leg = unknown
- hypotenuse = x
The hypotenuse is always opposite the 90 degree angle.
To tie together the opposite and hypotenuse, we'll use the sine ratio
sin(angle) = opposite/hypotenuse
sin(24) = 8/x
x*sin(24) = 8
x = 8/sin(24)
x = 19.6687 approximately
x = 19.7 after rounding to the nearest tenth.
Side note: your calculator needs to be in degree mode
