Answer:
The angle measure for the bottom two angles in order for the triangle to be classified as an isosceles triangle are 30 degrees each
Explanation:
An isosceles triangle has two of its angles equal.
Given that one angle is 120 degrees, assuming the remaining angles are equal, since the sum of the angles in a triangle is 180 degrees, we have:
120 + x + x = 180
120 + 2x = 180
2x = 180 - 120 = 60
x = 60/2 = 30
Each of the remaining angles measure 30 degrees

Answer:
around 22, or 21.98
Step-by-step explanation:
![s1 = {r}^{2} \times \pi = 9 \times 3.14 = 28.26](https://tex.z-dn.net/?f=s1%20%3D%20%20%7Br%7D%5E%7B2%7D%20%20%5Ctimes%20%5Cpi%20%3D%209%20%5Ctimes%203.14%20%3D%2028.26)

![s3 = 28.26 - (3.14 \times 2) = 28.26 - 6.28 = 21.98](https://tex.z-dn.net/?f=s3%20%3D%2028.26%20-%20%283.14%20%5Ctimes%202%29%20%3D%2028.26%20-%206.28%20%3D%2021.98)
Answer:
16 2/3
Step-by-step explanation:
If we divide 300 by 100, then we get 1/100th percent of 300, which is 3. Divide the difference, 50 by 3 and thats the percent we save.
16 2/3
Hope this helps!
4(4x + 6) - 7 = 77 - 4x......distribute thru the parenthesis
16x + 24 - 7 = 77 - 4x ...simplify
16x + 17 = 77 - 4x ...addition property of equality....add 4x to both sides
16x + 4x + 17 = 77 ...subtraction property ...subtract 17 from both sides
16x + 4x = 77 - 17...combine like terms
20x = 60 ....division property....divide both sides by 20
x = 60/20
x = 3
