Answer: 21/-20

Why?
To find skip you do the difference of Y/ the difference of x. So...
12+9/ -19-1 = 21/-20

Hope this helps :D

How do you do this? This is trig mixed sides

Marina CMI [18]

In this triangle,

$\cos45^\circ=\dfrac n{60}$

You should know that

$\cos45^\circ=\dfrac1{\sqrt2}$

so that

$n=\dfrac{60}{\sqrt2}=30\sqrt2\approx42.4$

What is the gcf of 25, 35 and 45

nekit [7.7K]

GCF of 25, 35 and 45 is 5

Step-by-step explanation:

The greatest factor that divides all given numbers is called the greatest common factor.

In case of 25, 35 and 45, the greatest number that will divide all three will be the GCF

For that, we have to find the factors of all numbers

$25 = 1,5,5\\35 = 1,5,7\\45 = 1,3,5,9$

By observing the factors we can say that the greatest common factor is 5

Hence,

GCF of 25, 35 and 45 is 5
