Answer is 71.3
31*2.3=71.3
All the angles in a triangle= 180 degrees.
2x+5x+3x= 180
Combine like terms.
10x= 180
Divide by 10 into both sides.
x= 18
Now, plug that into <L.
3(18)= <L
<L= 54 degrees
I hope this helps!

Answer: r = -9
Step-by-step explanation:
We will use the amount Jermaine used to determine the admission price, since that is not given to us. The total amount he paid is equal to the sum of the price of the tickets and the amdission price, a. We get the equation 43.75 = 1.25 * 25 + a a = $12.5 Now, if a person comes to the fair and pays for only the rides and admission, we can form an equation in x, the number of ride tickets, and y, the total cost incurred by that person. y = 1.25x + 12.5 Here, y is the total cost, 1.25 is the price per ticket, x is the number of tickets and 12.5 is the admission cost.
Hope this help.
