Answer:
24 feet
Step-by-step explanation:
The side adjacent to the angle is given, and the hypotenuse of the triangle is the unknown. The cosine relation applies:
Cos = Adjacent/Hypotenuse
hypotenuse = ladder length = (5 ft)/cos(78°) ≈ 24.0 ft
The ladder is about 24 feet long.
You need to form an algebraic equation. 4.5+h=7.3 therefore h= 7.3 - 4.5 when you take 4.5 to the other side it becomes negative therefore the answer is 2.8.
Answer:
3x=6
Step-by-step explanation:
10 + 5x =8+12
10 +5x = 20
Subtract 10 from each side
10-10+5x=20-10
5x= 10
Divide by 5
5x/5 = 10/5
x = 2
We want 3x
3(2) = 6
3x=6
That sounds correct to me.
