nalin [4]

Answer:

20.49 feet to the nearest hundredth.

Step-by-step explanation:

Using the Pythagoras Theorem:

Dvinal [7]

Answer:

\sqrt{85} /2

Step-by-step explanation:

lets find hypotenuse( longest side) first

let other two samller sides be a and b and hypotenuse be c

pythagorsd theorem

a^2 + b^2 =c^2

9^2 + 2^2 =c^2

81 + 4=c^2

85 =c^2

\sqrt{85} =c

take theta as reference angle

cosec theta=hypotenuse/opposite

=\sqrt{85} / 2

Y=-2x+6 3y-x+3=23 how do i solve this finding the x and the y
zheka24 [161]

Answer:


Step-by-step explanation:

 given system :

y=-2x+6 ........(1)

3y-x+3=23.........(2)

Substitute y = -2x+6 into (2) and solve for x :

3( -2x+6) - x +3 = 23

- 6x +18 - x +3 =23

- 7x = 2

x =- 2/7

Substitute  : x into (1) : y = -2 (-2/7)+6 = 46/7
