Answer:
(-6+y)-3y=28
-2y-6=28
-2y=34
y=-17
Then,
x=-6-17
x=-23
Step-by-step explanation:
Answer:
24
Step-by-step explanation:
12 x 2
Answer:
x = 107
Step-by-step explanation:
44+29+107=180
a triangle equals 180 with all the degrees added together :)
Yes you are correct very nice job!
Answer: last option (5π√146 units²)
Step-by-step explanation:
To solve the exercise you must apply the formula for calculate the lateral area of a cone, which is shown below:
![LA=r*L*\pi](https://tex.z-dn.net/?f=LA%3Dr%2AL%2A%5Cpi)
where r is the radius but L is the slant height.
As you can see in the figure attached:
![r=5](https://tex.z-dn.net/?f=r%3D5)
But you need to find the slant height with the Pythagorean Theorem (L would be the hypotenuse):
![L=\sqrt{11^2+5^2}=\sqrt{146}](https://tex.z-dn.net/?f=L%3D%5Csqrt%7B11%5E2%2B5%5E2%7D%3D%5Csqrt%7B146%7D)
Substitute into the formula, then:
units²
