Find the missing angle measure in each figure​

Mathematics
1 answer:
Brrunno [24]3 years ago
8 0

Answer:

x = 100°

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

here n = 7, hence

sum = 180° × 5 = 900°

Sum the given interior angles and equate to 900

x + 155 + 116 + 135 + 135 + 116 + 143 = 900

x + 800 = 900 ( subtract 800 from both sides )

x = 100°

The amount of packing material is 1506 cubic inches

<h3>How to determine the amount of packing material?</h3>

The given parameters are:

<u>Can</u>

Radius, r = 7 inches

Height, h = 18 inches

<u>Box</u>

Base dimension, l = 15 inches

Height, h = 19 inches

The volume of the can is:

V = \pi r^2h

So, we have:

V_1 = 3.14 * 7^2 * 18

V_1 = 2769

The volume of the box is

V =l^2h

So, we have:

V_2 =15^2 * 19

V_2 =4275

The amount of packing material is;

Amount = V2 - V1

This gives

Amount = 4275 - 2769

Evaluate

Amount = 1506

Hence, the amount of packing material is 1506 cubic inches

If a rectangle is 2 meters more than its width, and the area of it is 80 square meters, what is the length and width?
bezimeni [28]
Ok I think it means that the length l of the rectangle is 2 m more than is width w...
The area is A=l*w=(w+2)*w=80
so: w^{2} +2w-80=0
Solving this equation (using the quadratic formula) you get 2 solutons. The only acceptable is the positive one, i.e. w=8 m, the length will then be l=w+2=8+2=10m.
