Answer:

A° = 44.42°

Step-by-step explanation:

Soh Coh Toa
Soh: sin(theta) = Opp/Hyp

Coh: cos(theta) = Adj/Hyp

Toa: tan(theta) = Opp/Adj

We are using Coh: cos(theta) = Adj/Hyp because we need to find Angle A and that 5 is Adjacent and 7 is the Hypotenuse.

cos(A°) = 5/7

A° = cos^-1 (5/7)

A° ≈ 44.4153086

A° = 44.42°

Show that points A(-3,-2),B(3,1), and C(5,2) lie on a straight line

agasfer [191]

Answer:

Step-by-step explanation:

If A, B, and C are on the same line, they have the same slope.

k is slope.

k(AB) = $\frac{(1+2)}{(3+3)} =\frac{1}{2}$ ;

K(BC)= $\frac{2-1}{5-3} =\frac{1}{2}$ ;

So k(AB)=K(BC)

It is a rectangle and I need to get x and the top is -1+4x and the bottom is 3x+3 I’m in 8th grade geometry

Andrej [43]

The value of x is 4.

Step-by-step explanation:

Consider a Rectangle ABCD

AB as Top

CD as Bottom

AB = -1 + 4x

CD = 3x + 3

To Find:

x = ?

Solution:

In a Rectangle ABCD

Opposite sides of rectangle congruent,

AB = CD

Top = Bottom

on substituting we get

$-1+4x=3x+3\\\\4x-3x=3+1\\\\x=4\\\therefore x =4$

The value of x is 4.
