Answer:
≈ 35.1 ft
Step-by-step explanation:
The model is a right triangle with ladder being the hypotenuse and the angle between the ground and the ladder is 70°
Using the cosine ratio, with l being the length of the ladder.
cos70° = 
= 
( multiply both sides by l )
l × cos70° = 12 ( divide both sides by cos70° )
l = 
≈ 35.1 ( to the nearest tenth )
The ladder is approx 35.1 ft long
Answer:
x = 17deg
Step-by-step explanation:
Let angle y be the unknown angle IN THE TRIANGLE.
Angle y = 180 - 90 - 73
= 17deg
Angle x = Angle y (Alternate angles on 2 parallel lines)
Angle x = 17 deg

Hello,
This is simple :)
<span>First divide:
How many times does 16 go into 7? : 0
7 GOES into 16, 0 times, now we have ; 0.
Next, multiply 16(0):0
Now, subtract 7-0
=7
Bring 0 down... so now we have 70... how many times can you divide 16 into 70? : about 4 times.
Now we have: 0.4
Multiple 16 by 4
= 64 : SUBTRACT 64 from 70
=60
Bring Down: 0; this gives us 60.
Divide:
How many times can 16 go into 60? : About 7 times
No we have : 0.437..
Bring down 0; gives us 600: how many times can 16 go into 600?: About 5 times.
Now, we have 0.4375.
Thus, 7/16 = 0.4375.

√a can be written as (a)^(1/2)
∛a can be written as (a)^(1/3) and so on,
so √15=(15)^(1/2)
