To rotate a figure 90 degrees counter clockwise, switch the X and Y coordinates, and then multiply the new X value by -1
Find the original points:
(2,2) becomes (-2,2)
(7,1) becomes (-1,7)
(8,-4) becomes (4,8)
Put the 50.605 over 1 then multiply by 1 to eliminate the decimal then multiply the numerator and denominator by 10^3=1000. Find the GCF which is 5 and divide the numerator and denominator by 5 then simplify the improper fraction
Answer:
8.090169944 or rounded 8.1
Step-by-step explanation:
Use SOH CAH TOA
Look at x and where it is and what you have.
First thing is to get an angle to use, 36, then to set up your equation.
___(36)=___
Figure out what you have.
You have the hypotonouse, 10, and need the adjacent,x, so you use the equation that involves H for hypotonouse and A for adjacent.
You set up your equation using COS, as you are using CAH.
Cos(36)=x/10
X is over ten sure to CAH C-cos A-adjacent and H-hypotonouse
Switch it around to make it equal to x
10*Cos(36)=x
You input it into your calculator. [10] [COS] [36] [ENTER] and you get the answer.
Round however is needed.
