60 would be the interior angle of angle 3 however angle 3 is the exterior angle so it is 360-60=300

Answer:

120 ft

Step-by-step explanation:

A slope of 12/100 means for every 12 units of distance you move horizontally you descend by 100 of the same units vertically. Assuming now that the slope does not change, i.e it remains constant throughout your trip; descending by 1000 ft should mean you have moved horizontally by 120 ft so that the slope is maintained.

x/1000 = 12/100

x = 120 ft

Help me please. Stuck on this question.

Since you know that the top angle is 90 degrees and the bottom is 45 that tells you that the only other angle has to be 45 degrees which means the side it opens up into is also 3radical2 so then you do a^2+b^2=c^2 and you get 4radical3

The sum of two numbers is 60. Their difference is 24. Find the numbers.
prisoha [69]

Answer:

The Answer is: The first number is 42 and the second number is 18.

Step-by-step explanation:

Let f = first number and s = second number.

f + s = 60

f - s = 24

Solve for f:

f = 24 + s

Substitute:

24 + s + s = 60

2s = 36

s = 18, the Second Number

Solve for f:

f = 24 + s

f = 24 + 18 = 42, the First Number

Proof:

42 + 18 = 60

60 = 60

Then:

42 - 18 = 24

24 = 24

Hope this helps! Have an Awesome Day!! :-)
