Answer: The ladder is 5.3 m long
Step by step solution
1. Draw out the scenario, ie a right triangle where the hypotenuse is the ladder, the wall is 4.5m and the angle the ladder and the ground makes 58 degree.
2. Soh, Cah, Toa
The wall is opposite, the ground is adjacent, and the ladder is hypotenuse
Sine (58) = 4.5/h
3. Solve for hypotenuse
h * sine (58) = 4.5
h = 4.5/sine (58)
h = ~ 5.3 m
Answer:
18 years
Step-by-step explanation:
2(8+x) = 34+x
16+2x = 34+x
-18 = -x
I’m pretty sure the answer is 4x+5
Answer:
4. 8.0
5. 27.6
6. 35.5 degrees
Step-by-step explanation:
#4- Cos 48= x/12
0.669131= x/12
x=8.0
#5
Sin 78= 27/x
0.978=27/x
0.978x=27
x=27.6
#5
Tan X= 15/21
tan x= .714
inverse tan= 35.5 degrees
