I think the answer would be C. (btw, you should charge your phone/tablet, lol)
Answer:
7.) 16.7
Step-by-step explanation:
7). First you have to find the length of the line with the triangle that is at a 90 angle with the longest side of the triangle
Using the pythagrorem theorem a² + b² = c²
4² + b² = 5²
b² = 5² - 4²
b² = 25 - 16
b² = 9
√b² =√9
b = 3
next you do the same thing to find the missing segment of the longest side
3² + b² = 13²
b² = 169 - 9
b² = 160
b = √160 or ≈ 12.7
12.7 + 4 = 16.7
so 16.7 is the length of that side
An equilateral triangle has 3 equal sides and angles. Each angle is
60 degrees.
37.8*0.08=3.024
37.8-3.024=34.776
round to the nearest tenths place for currency
and the answer is $34.78
