Hey there!
Let's set up an algebraic equation to represent this problem:
In order to get rid of the squared, we need to take the square root of both sides, therefore, our answer is:
Your answer is the square root of 20.
Hope this helps!
Answer:
about 3.0 meters
Step-by-step explanation:
30-60-90 triangle rules:
smallest side is half the hypotenuse
the longer side of the 90 degree is the short side times sqrt of 3
Answer:
Step-by-step explanation:
The formula for the area of a sector is
where θ is the measure of the central angle and r is the radius.
Our central angle is a right angle and the radius is 4, so filling in the formula looks like this:
and
16 divides by 4 evenly, so
A = 4π.in²
If we multiply 4 by the value of π and then round, that number, to the nearest hundredth, is
A = 12.57 in²
Answer:
CED and BEC
Step-by-step explanation
supplementary angles =180
they are next to each other
trust me.
Answer:
4/3
Step-by-step explanation:
The exponential form is (3x+4)^4=4096
Take the fourth of both sides:
3x+4=plus or mins 8
3x+4=8 or 3x+4=-8
So
3x=4 or 3x=-12
x=4/3 or x=-4 (this sound won't work because 3x+4 becomes neg)
So only sol 4/3.
