Answer

First find the value of x:

5x + 55° = 2x + 100, because these angles are corresponding angles so they are equal.

5x + 55 = 2x + 100

-2x. -2x

3x + 55 = 100

-55. -55

3x = 45

÷ 3. ÷3

x = 15

Angle 2 is supplementary to angle 5x + 55 or 130°, so angle 2 equals 180 - 130 = 50°

A can of tuna has a volume 18pi cm3 and a height of 2 cm. Find the area of the label that wraps around the entire can and does n

Sphinxa [80]

Answer:

The area of the label is $12\pi\ cm^{2}$

Step-by-step explanation:

step 1

Find the radius

we know that

The volume of the cylinder (can of tuna) is equal to

$V=\pi r^{2} h$

In this problem we have

$V=18\pi\ cm^{3}$

$h=2\ cm$

substitute and solve for r

$18\pi=\pi r^{2} (2)$

Simplify

$18=r^{2}(2)$

$r^{2}=9$

$r=3\ cm$

step 2

Find the lateral area of the can

The lateral area of the cylinder (can of tuna) is equal to

$LA=2\pi rh$

we have

$r=3\ cm$

$h=2\ cm$

$LA=2\pi (3)(2)=12\pi\ cm^{2}$

Need help on answering number 13.

Genrish500 [490]

You can find the value of y when you substitute the x value into the equation.

Since x = 3, the equation becomes:
y = 3 + 5

The answer to question 13 is y = 8
