1. Anwser=53.3 (do 40*3 then anwser x 4)
2anwser=120
Answer:
It should have 20 vertices, and the name is dodecahedron
<h3>When two dice are thrown, the total number of sample spaces is 36. Hence, the probability of getting a sum of prime numbers = 15/36 = 5/12.</h3>
Answer:
Angle EFG = 82 degrees; Angle GFH = 98 degrees
Step-by-step explanation:
Linear pairs are angles that are placed side by side. When you add them together, you get 180 degrees.
Show work:
3n + 22 + 4n + 18 = 180
7n + 40 = 180
7n = 140
n = 20
Plug in the variable:
Angle EFG:
3(20) + 22
60 + 22
Angle EFG = 82 degrees
Angle GFH
4(20) + 18
80 + 18
Angle GFH = 98
Check:
98+ 82 = 180 degrees
180 degrees was the total so the answer is correct.
Ok so first 70.50-52.01= 18.49 - .22= 18.27
