Answer:
2.4
Step-by-step explanation:
From the Euclidian theorem TR*TS = RS*h
3*4 = 5*h
12 = 5h divide both sides by 5
2.4 = h
Answer:
This is a 30-60-90 right triangle.
<u>The ratio of sides:</u>
<u>Compare with the given values:</u>
- a = 3√3, b = y, c = x
- y = 3√3*√3 = 9
- x = 2*3√3 = 6√3
For this case we have the following property of the sum:

What we need to know is that the name of this property is:
Identity property of the sum.
What this property establishes is:
Every number added to zero is equal to the same number.
Answer:
the number sentence show:
Identity property of the sum.
I hope you can understand my work.
Step-by-step explanation:
because we can also find out the value of x in second equation like this
3x=21
x=21/3
x=7
