Because this is a triangle, all three angles put together equals 180 degrees.
We can add the angles together and set them equal to 180 to solve for the value of y.
y + y - 12 + 56 = 180
Combine like terms.
2y + 44 = 180
Subtract 44 from both sides.
2y = 136
Divide both sides by 2.
y = 68
<u>The value of y is equal to 68 degrees.</u>
Answer:
Answer: 6 3/4
Step-by-step explanation:
You have to mulitply 2 x 4 + 1 = 9 and 4 is going to be the denomiator and how much can 3 can go into 9 only 3 times and that going to be on top of the denomiator and 2 x 3 = 6
It would b 3.2 bc the 2 isn't higher than a 5 so it says the same..
The shape has 11 sides.
Using the angle formula for polygons:
The sum of all the interior angles is:
11-2 x 180 = 9 x 180 = 1,620 degrees.
For one angle divide the total by number of sides:
1620 / 11 = 147.27 which rounds to 147.2
The answer is D.
