Answer:
To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.
So (m+n)/2= 7
To find m+n, multiply both sides by 2
m+n=14
Final answer: C
Answer:
49.4
Step-by-step explanation:
So, 1 Gallon = 3.8 Liters. We need to find how many liters are in 13 gallons.
All we need to do is multiply our 3.8 liters (1 gallon) by 13 to find out how many liters 13 gallons is.
3.8 x 13 = 49.4
Your answer is 49.4.
