Answer:
X = 75
Step-by-step explanation:
here, DY || FS ,
SO, Angle DFS = Angle JDY
( Corresponding angle pair )
Angle JSF = Angle JYD
( Corresponding angle pair )
Hence, triangle JDY ~ JFS ( By AA CRITERIA )
Now, JY / YS = JD / DF
=》42 / 63 = 50 / X
=》X = 50/42 × 63
=》X = 75
i hope you got it
Answer:
50.27 in^2
Step-by-step explanation:
the diameter (d) of the pizza is 8 in, and the radius (r) is half the diameter, so therefor the radius is 4 in
A=πr2=π·42≈50.26548
Question 1:
Add all the ratio numbers.
2+6+7=15
Now, divide that from 45, which is the given perimeter
45/15=3
Now, multiply the whole ratio by 3.
6:18:21
The shortest side is 6 inches.
Question 2:
Add all the ratio components.
17+16+12=45
Divide that by 180, the total degrees in a triangle.
180/45=4
Multiply that with 17 (largest ratio component).
You get 68, which is your answer.
Question 3:
(2x+7)/(3x-4) = 11/2
This proportion is quite simple and can be solved by setting the numerator equal to the numerator and the denominator equal to the denominator.
2x+7=11
3x-4=2
If you solve both of these, the value of x is 2.
That's your answer.
(Note: this is only a special case where you can do this)
Hope this helps! :)
Answer:
⅔
Step-by-step explanation:
Slope of AB = (3-8)/(5-3) = -5/2
Slope of the Perpendicular:
-1/slopeAB
-1/(-5/2) = 2/5 or 0.4
