Answer:
<em>x = -11</em>
Step-by-step explanation:
<u>Equations</u>
The image shows a right triangle with angles 70°, 90°, and x+31.
The sum of the internal angles of a triangle is 180°, thus:
70 + 90 + x + 31 = 180
Simplifying:
191 + x = 180
Subtracting 191:
x = 180 - 191
x = -11
Answer is 70 because multiply it by 2 and then add
Answer:448.5
Step-by-step explanation: first you have to see what 50% of 299 is so you do 299/2=149.5 so now they are marking it up so you do 299+149.5 =448.5
Answer:
2,712.96 yd³
Step-by-step explanation:
The formula for finding the volume of a cylinder:
πr²h
π (in this case) = 3.14
r = radius
h = height
In this picture, we are given all of the values we need to set up and solve this equation.
r = 12 yd
h = 6 yd
3.14(12)^2 · 6
3.14(144) · 6
452.16 · 6
2,712.96
It has one solution Bc there is only one variable
