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.
1a= (2x+5)+3x+15
1b= (2(4)+5)+3(4)+15=40
2a= (3x+5)•(4x-3)
2b= (3(2)+5)•(4(2)-3)=55
2c= 2(x) or 2(2)
How I got 2c is the perimeter of the rectangle LMNP subtract from (2(2)+9)+(2(2)+9)=26 which in return means you subtract 30 from 26 and get 4 which is 2(2) or 2x
8:24
4:12
100:300
All you have to do is multiply both sides by the same number to get an equivalent ratio.
Answer:
83,400
Step-by-step explanation:
Just carry the decimal point over to the right 4 places.
1,000. 4,200 / 21 = 200. 5 * 200 = 1,000
