Find the value of x. Show all work.
Mashutka [201]

Answer:

x = -8°

Step-by-step explanation:

Angle 2

Since the triangle is isosceles, Angle 2 is the same as the missing angle

So angle 2 would be:

180 - 34 = 2(angle 2)

So 146 = 2(x + 81)

146 = 2x + 162

146 - 2x = 162

-2x = 16

x = -8

Check

146 = 2(-8+81)

146 = 2(73)

146 = 146

Correct!

If my answer is incorrect, pls correct me!

Two similar cylinders have radii of 15 inches and 6 inches. What is the ratio of the surface area of the small cylinder to the s
Levart [38]

Answer:

4:25

Step-by-step explanation:

Given that,

r₁ = 15 inches, r₂ = 6 inches

The area of the cylinder is given by :

A=2\pi rh+2\pi r^2

The ratio of surface areas of two cylinders,

\dfrac{S_2}{S_1}=\dfrac{2\pi r_2h_2+2\pi r_2^2}{2\pi r_1h_1+2\pi r_1^2}\\\\\dfrac{S_2}{S_1}=(\dfrac{r_2}{r_1})^2\\\\=\dfrac{6}{15}^2\\\\=\dfrac{4}{25}

Hence, the required ratio is 4:25.
