P = 4s
P = (120)^1/2
4s = sqrt120
s = sqrt120/4

A = 2s
2*sqrt120/4 = sqrt120/2
Number 5 is the square root of 120 divided by 2

P= sqrt120
P = 4s
4s= sqrt 120
4s = 2sqrt 30
s = (sqrt 30)/2
Area = s*s or s^2
A= ((sqrt 30)/2)^2
A= 30/4
A= 7 1/2 cm^2

Answer:

the corresponding sides and angles would be a pair of matching angles or sides that are in the same spot in two different shapes.

Step-by-step explanation:

So look at triangle AWXV and check each side....does side AW correspond with other triangle AX - meaning they are the same?

Repeat to find the same angle in each triangle that matches.

Solve the equation
inysia [295]

Answer:

x ≈ 1.32, x ≈ - 5.32

Step-by-step explanation:

Given

x² + 4x - 7 = 0 ( add 7 to both sides )

x² + 4x = 7

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(2)x + 4 = 7 + 4

(x + 2)² = 11 ( take the square root of both sides )

x + 2 = ± \sqrt11} ( subtract 2 from both sides )

x = - 2 ± \sqrt{11}

Thus

x = - 2 - \sqrt{11} ≈ - 5.32 ( to 2 dec. places )

x = - 2 + \sqrt{11} ≈ 1.32 ( to 2 dec. places )

In equilateral triangle RST, R has coordinates (0, 0) and T has coordinates of (2a, 0). Find the coordinates of S in terms of a.
FromTheMoon [43]
The x  coordinate of S will be 1/2 * 2a = a.
and since  the half triangle is 30-60-90 the y coordinate will be sqrt3 a

so S  is (a , sqrt3a)
