Answer:
35+52+3(x+2)=180(sum of interior angle of triangle)
3(x+2)=180-87
x+2=93/3
x=31-2=29 is your answer.
Step-by-step explanation:
I think the answer is obtuse. An obtuse triangle has one angle that is greater than 90 degrees and two that are less than 90 degrees. Therefore, I think the answer is an obtuse triangle.
Answer:
A. 1,177.58 cm³
Step-by-step explanation:
Volume of hemisphere = ⅔πr³
Radius (r) = 16.51 ÷ 2 = 8.255
π = 3.14
Plug in the values
Volume of the hemisphere-shaped cup = ⅔ × 3.14 × 8.255³
= 1,177.57783 ≈ 1,177.58 cm³
Answer:
No Solution
Step-by-step explanation:
For system of equations, you must equal the equations to each other like shown below:
![3x + 1 = 3x + 7](https://tex.z-dn.net/?f=3x%20%2B%201%20%3D%203x%20%2B%207)
Solve for x by subtracting 3x from both sides of the equation:
≠ ![7](https://tex.z-dn.net/?f=7)
