5t+5=30
divide both sides by 5
t+1=6
minus 1 both sides
t=5
6a + 15
hope this helped :)
Answer:
<B =121
Step-by-step explanation:
If the angles form a linear pair, they add to 180
6x-19 + 11x-22 = 180
Combine like terms
17x -41 = 180
Add 41 to each side
17x-41+41 = 180+41
17x = 221
Divide by 17
17x/17 =221/17
x =13
<b = 11x-22 = 11*13 -22 = 143-22 =121
