0.54+12.1 =12.64
2.55+145.05=147.6
25.59+1.2=26.79
23.04+124.1+34.06=181.2
1.51+3.07+4.18=8.76
You’re welcome
Answer:
26.6 minutes
Step-by-step explanation:
Set up a proportion
3/8 = 10/x
cross multiply
3x = 80
x = 26.6
7/10 > 4/10 because 7/10 is bigger than 4/10
7/10 = 0.7
4/10 = 0.4
In order to fully understand the problem, it is best to sketch it. Sketching the system, we will see that the system forms a triangle where the angle of elevation is 36 degrees. We are asked to find the hypotenuse. We can use a trigonometric function. It should be noted that one of the sides should also be given in order to calculate the hypotenuse. Trigonometric functions that can be used are:
sin(theta) = opposite / hypotenuse
cos(theta) = adjacent / hypotenuse
