Answer:
-55
Step-by-step explanation:
2nd term=> -1 + -2 × (2 - 1)
3rd term=> -1 + -2 × (3 - 1)
:
28th term=> -1 + -2 × (28 - 1)
=> -1 - 54 = -55
Answer:
Smallest angle of triangle=26 degrees
Second angle of triangle =78 degrees
Third angle of triangle =76 degrees
Step-by-step explanation:
Let x be the smallest angle of triangle
Second angle of triangle=3x
Third angle of triangle=x+50
We know that
Sum of angles of triangle=180 degrees
Using the property
![x+3x+x+50=180](https://tex.z-dn.net/?f=x%2B3x%2Bx%2B50%3D180)
![5x=180-50](https://tex.z-dn.net/?f=5x%3D180-50)
![5x=130](https://tex.z-dn.net/?f=5x%3D130)
![x=\frac{130}{5}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B130%7D%7B5%7D)
degree
Smallest angle of triangle=26 degrees
Second angle of triangle =3(26)=78 degrees
Third angle of triangle =26+50=76 degrees
