It’s isosceles because 2 acute angles and one 90 degree angle makes an isosceles triangle
Answer:
All you have to do is divide 3 4/5 by 2 which is<u> 1 9/10</u>
Step-by-step explanation:
Answer:
The answer is 6 3/4
Step-by-step explanation:
Well first you are gonna have to extract the whole numbers in this question. the whole numbers are 3, 2, and 1. 3 + 2+ 1 is 6. Now we have to add the fractions. Since they all have different denominators we will have to find a multiple that they all have. all three of the denominators can be multiplied to get to 12. 1/6 times 2/2 = 2/12. 1/3 times 4/4 = 4/12. ¼ times 3/3 = 3/12. Now that we have the three denominators that are the same, we can add the fractions. 2/12 + 4/12 + 3/12 = 9/12. 9/12 simplified is 3/4. This means that the answer is 6 ¾.

I found the value of x to be 6 by adding the two equations together and setting them equal to 180.
2x^2+3x-5+x^2+11x-7=180
When you solve for x you get x=6
Then you plug 6 in for x in each angle. The first angle is 85 and the second is 95.
