We have to check if LHS = RHS
First solve LHS
No it was the last answer. Because decrease is -5 and -5 which makes -10
Answer:
13 degrees
Step-by-step explanation:
Let x be the degree measure of the angle's complement
Then we have the other angle is x + 64
Because the 2 angles complement each other so the sum of the 2 angles is 90
So we have the equation: 2x + 64 = 90
<=> 2x = 26
<=> x = 13
After 40 minutes, Ralph has already painted (40/60)/12=1/18 of the fence
Lisa's speed is 1/15 fence/hour, Ralph's speed is 1/12 fence/hour, hence when they help each other their combined speed is 1/15+1/12=3/20
Thus we need to solve 3/20*x=17/18 thus x=170/27 hours (approx 6 hours 15 mins)
