Answer:
48.2°
Step-by-step explanation:
If a 15' ladder is leaned up against a building so that the bottom of the ladder is 10' from the base of the building, what angle does the ladder make with the ground
Let the angle the ladder makes with the ground be represented by x
We solve the above question using the Trigonometric function of Cosine
cos x = Adjacent/Hypotenuse
Adjacent = 10 inches
Hypotenuse = 15 inches
Hence,
cos x = 10/15
x = arc cos (10/15)
x = 48.189685104°
Approximately = 48.2°
Therefore, the angle the ladder makes with the ground is 48.2°
Answer:
102cm³
Step-by-step explanation:
Imagine the shape as two rectangular prisms, a small one on top of a bigger one. Find their volumes individually, and then add them together:
<u>Small rectangular prism</u>
Volume=length*width*depth
=2*3*(7-5)
=6*2
=12cm³
<u>Bigger rectangular prism</u>
Volume=length*width*depth
=6*3*5
=6*15
=90cm³
12+90=102cm³
4.221 is greater because of the .221

Answer:
It's choice B, 5, 8, 11
Step-by-step explanation:
The 1st number is odd, less than 5, so it might be 1 or 3, the probability is 2/10
But if the sum has to less than 5, than *when 1st number is 1, the second number can only be 1.2.3
and *when 1st number is 3, 2nd can only be 1
*1: 3/100
*2: 1/100
3/100+1/100=4/100
so the answer should be (4/100)/(2/10)=2/10=1/5
I'm not so sure if I'm right
