What is m∠B? (view attached file)

Mathematics
1 answer:
Pepsi [2]2 years ago
4 0

Answer:

m∠B = 141°

Step-by-step explanation:

sides of polygon (n) = 7

sum of angles of polygon = {(n - 2) * 180°}

= {(7 -2)*180°}

= 5* 180°

= 900°

Now,

m∠B = 900° - 148° - 142° - 130° - 129° - 120° - 90°

m∠B = 141°

Mario’s company makes unusually shaped imitation gemstones. One gemstone has 14 faces and 10 vertices. How many edges does the g
Ivan
The gemstone has 22 edges.

We use Euler's formula on this:

F + V - E = 2

Substituting our information, we have:

14 + 10 - E = 2

Combining like terms, 
24 - E = 2

Subtract 24 from both sides:
24 - E - 24 = 2 - 24
-E = -22

Divide both sides by -1:
-E/-1 = -22/-1
E = 22

a) a + c = 90

d) a + b + c + 30 = 180

e) The angles marked a and b are vertical

f) The angles marked a and c are complementary.

Step-by-step explanation:

A complementary angle is and angle that has a sum of 90 degrees. A vertical angle is 2 angles facing each other, that are completely identical. 180 degrees is the sum of a strait line. 90 degrees is a right angle.
