<span>All the angles of a triangle add up to 180 degrees.
Since two of the angles are the same, we can write:
2A+B=180
Where 2A accounts for the two angles that are the same.
We are given the relation:
B=A+30
We can plug this into our first equation:
2A+A+30=180
</span><span>
Combine like terms and move the 30 to the other side:
3A=150
Divide both sides by 3:
A=50
We can solve for B by plugging A back into our relation:
B=50+30
B=80
To check: 80+50+50 so we are correct.</span>
Answer:
Step-by-step explanation:
y = -2x + 5 ⇒ 2x + y = 5
6x + 3y = 15 ⇒ 2x + y = 5
The two equations are equivalent, so there are infinitely many solutions.
29 2/19 + 5 1/2 = 29 4/38 + 5 14/38 = 34 18/38 = 34 9/19
