<h3>
Answer: 35 (choice C)</h3>
=============================================
Explanation:
For any triangle, the three interior angles always add to 180.
D+E+F = 180
(7b+1) + (2b+1) + (b+8) = 180
(7b+2b+b) + (1+1+8) = 180
10b+10 = 180
10b = 180-10
10b = 170
b = 170/10
b = 17
Use this value of b to find the three angle measures
- D = 7b+1 = 7*17+1 = 119+1 = 120
- E = 2b+1 = 2*17+1 = 34+1 = 35 degrees
- F = b+8 = 17+8 = 25
As a check,
D+E+F = 120+35+25 = 120+60 = 180
which helps confirm the correct answers.
Answer:
-3y^2 + y + 100
Step-by-step explanation:
Combine like terms.
-3y+4y = 1y or "y"
Add "y" back into the equation.
-3y^2 + y + 100
The equation cannot be simplified any further.
I hope this helped!
Answer:
the third one from the top
Step-by-step explanation:
Answer:
The answer is A
Step-by-step explanation:
The answer is A because a circle is a circle and it doesn't have any sides and it's a bunch of points that are the same distance from each other creating a circle like object.
Hope this helps :))
