## KE8717504 3 years ago In a triangle, the measure of the first angle is twice the measure of the second angle. The measure of the 3rd angle is 68 degrees more than the measure of the 2nd angle. Use the fact that the sum of the measures of the 3 angles of a triangle is 180 degrees to find the measure of each angle. The measure of the smallest angle is??

1. ajprincess

Let us assume the scond angle to be x. Then first angle=2x Third angle=x+68 x+2x+x+68=180 Can u find x nw?

2. KE8717504

ok so im going to combine like terms right?

3. ajprincess

ya. that's the first step.

4. KE8717504

ok so i get 4x+68=180. so now i subtract 68 from both sides?

5. ajprincess

ya

6. KE8717504

then i get 4x=112 so i divide by 4 on both sides and get 28? After that how do i find the measure of the smallest angle?

7. ajprincess

ya

8. KE8717504

Ok so how do i find the measure of the smallest angle?

9. ajprincess

The value of x is the measure of small angle.

10. KE8717504

so 28 is the measure of the smallest angle?

11. ajprincess

ya.:)

12. KE8717504

what would the measure of the 2nd largest angle be?

13. ajprincess

2x

14. KE8717504

that's not right it said.

15. KE8717504

It says what would the measure of the 2nd largest angle be?

16. ajprincess

2x=?

17. KE8717504

what do i multiply there where that x is ?

18. KE8717504

would i do 2(28)?

19. ajprincess

yes

20. KE8717504

and how would i find the measure of the largest angle?

21. ajprincess

x+68=?

22. KE8717504

so 28+68?

23. KE8717504

so would the largest angle be 96?

24. ajprincess

yes

25. KE8717504

If i post another one kind of similar will u help me on it? you are great

26. ajprincess

ya sure. post it.
