The equation which can be used to find the length of EF is option A which is EF=
.
Given the length of base of right angled triangle is 12 and the hypotenuse be 24.
We are to find the length of EF and tell which equation can be used to find the length of EF.
We know that pythagoras theorem applies in a right angled triangle.
Pythagoras theorem says that in a right angled triangle the square of the hypotenuse is equal to the sum of square of base and perpendicular.
In this triangle we are only given base and hypotenuse and we have to find EF which is perpendicular.
EF=
=
--1
=
=
Hence the equation which can be used to find the length of Ef is option A which is EF=.
Question is incomplete as it should include the figure also.

Answer:
70°
Step-by-step explanation:
Adjacent angles in a parallelogram are supplementary. The missing angle is ...
180° -110° = 70°
All u have to do is substract wich equals -129
Step-by-step explanation: We can write a ratio using the word "to", using a colon, or using a fraction bar.
Here, since we want our ratio in simplest form,
I would use a fraction bar.
Now, the problem asks us to compare
the number of boys to the number of girls.
We know that there are 12 boys
and we know that there are 15 girls.
So our ratio is 12/15.
However, this can be reduced to 4/5.
Let's factor the top and the bottom.
Top factors 4x + 20 = 4(x + 5)
Bottom x^2 + 2x - 15 = (x + 5)(x - 3)
The gcf is the largest value that will go into both the top and the bottom. In our problem the ONLY thing that will go into top and bottom is x + 5 so that is your GCF. (c)
