A homeowner leans a ladder against his house so that the top of the ladder makes a 31 degree angle with the house. What angle does the bottom of the ladder make with the ground? help! asap

Answers

Answer 1

Answer: If you put an imaginary line from the base of the ladder to the wall it would from a right angled triangle. The internal angles of a triangle all add up to 180degrees. With a right angled triangle, we know for sure one angle is going to be 90 degrees. One angle as you said is 31 degrees so you just add 31 and 90 which is equal to 121 then subtract it by that. SO:
180-(31+90)
180-121=59 degrees
or even easier
90-31= 59

Answers

Answer:

3.24 years

Step-by-step explanation:

We know that for the truck to become half of the value it has to decrease by %50 if it decreases by %15.4 the real question is 50/15.4=3.24 years because how many years will it take for %15.4 to pile up and eventually become %50
