First find out what 10 percent of 50 is
Do 50/10
I got 5
Then do 5 times 9 to get your answer
You should get 45. Thanks (:
Answer:
The correct option is x=3 , y=2
Step-by-step explanation:
According to the HL theorem if the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and one leg of another right triangle then the triangles are congruent.
By using this theorem we can set up the system of equations as follows:
x=y+1 ...(1)
2x+3= 3y + 3 ..(2)
Now we will plug the value y+1 of equation 1 in equation 2.
2x+3 = 3y+3
2(y+1)+3=3y+3
2y+2+3=3y+3
2y+5=3y+3
Now combine the like terms:
5-3=3y-2y
2=y
y=2
Now plug the value y=2 in equation 1.
x=y+1
x=2+1
x=3
Thus the values of(x.y) are{(2,3)}
Therefore the correct option is x=3 , y=2 .....

Answer:
Area = 20.52 cm^2 and Perimeter = 28.68 cm.
Step-by-step explanation:
Use Pythagoras theorem to find the base of the triangle.
a^2 = 6^2 - 3^2 = 27
a = sqrt27
b^2 = 9^2 - 3^2 = 72
b = sqrt72
Base = sqrt27 + sqrt72
= 13.68
So Area = 0.5 * 13.68 * 3
= 20.52 cm^2 (answer)
Perimeter = 9 + 6 + 13.68
= 28.68 ( answer).
