Answer: 23°, 65° and 92°
Step-by-step explanation:
a + b + c = 180 (The angles of a triangle equals to 180)
a = 4c (the largest angle is 4 times the smallest angle)
b = 4c - 27 (the final angle is 27 less than the largest angle)
c = c
Now that we have gotten the values for the variables in our equation, we plug them in:
4c + 4c - 27 + c = 180
Combine like terms:
4c + 4c + c - 27 = 180
9c - 27 = 180
9c = 180 + 27
9c = 207
Divide both side by 9
c = 23
a= 4c
a = 4 × 23
a = 92
b = 4c - 27
b = 92 - 27
b = 65
b = 65
Check:
a + b + c = 180
92 + 65 + 23 = 180
180 = 180
Answer:D
Step-by-step explanation:
you plug 4 in for x
f(4)=4^2+2(4)-3
=16+8-3
=24-3
=21
Answer:
i kind of need a picture of the grid to solve this
Step-by-step explanation:
First you add all the numbers together. So you add 82+93+75+89 to get 339. Once you get that, you divide it by the amount of numbers there are. In this case, it's 4. 339 divided by 4 is 84.75.
