Find the exact length of the third side .

The length of unknown third side of right triangle can be found by using Pythagoras theorem. a = √(c^2 - b^2) is the formula to find the length a:, b = √(c^2 - a^2) is the formula to find the length b: and c = √(a^2 + b^2) is the formula to find the length c:.

Step-by-step explanation:

a=9.8

Step-by-step explanation:

a(2)+2(2)=10(2)

2×2=4 10×10=100

subtract 4 from 4 and 100

a(2)=9.6

use the two buttons on the scientific caculator. Click 2nd, then click x2(close to bottom left)

you will get a bunch of numbers only put down the first 3. (9.79)

ROUND THIS

9.79=9.8

a=9.8

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
