If the measure of angle 2 is 125 degrees, find the measure of angle 3.PLS HELP

Tpy6a [65]

Angle C would be 55 degrees. A straight line is 180 degrees so you would do 180-125 which equals 55. Hope this helps!

Find the area of the parallelogram with vertices: (2,2,0),(5,3,0),(4,7,0),and(7,8,0).

PtichkaEL [24]

Answer:

13 square units

Step-by-step explanation:

Let the vertices of parallelogram are

A(2,2,0),B(5,3,0),C(4,7,0) and D(7,8,0)

Side AB= $B-A=-=$

Side AD=D-A= $-=$

We know that

Area of parallelogram=Magnitude of product of adjacent sides

$AB\times AD=\begin{vmatrix}i&j&k\\3&1&0\\5&6&0\end{vmatrix}$

$AB\times AD=$

$\mid AB\times AD\mid=\sqrt{x^2+y^2+z^2}$

$\mid AB\times AD\mid=\sqrt{0+0+(13)^2}$

Where x=Component along x-axis

y=Component along y- axis

z=Component along z-axis

$\mid AB\times AD\mid=13$ Square units

Hence, the area of parallelogram=13 square units

Use A as the subject of formula<br>p= A ( 1+r\100)

ZanzabumX [31]

Answer:

$A = \frac{100 P}{100+r}$

Step-by-step explanation:

Given $P = A( 1 + \frac{r}{100} )$

To make A as the subject of the formula we need to rearrange

Divide by $(1 +\frac{r}{100})$ throughout we get

$\frac{P}{1+\frac{r}{100}} = A$

$A = \frac{100P}{100 + r}$

1. (2r + 9)(2r-9) = 4r^2 -81
+ (2r - 9)^2 = 4r^2 - 36r + 81
= 8r^2 - 36r

2. 12 - 5 [ a^2 + a - 1 ] + 5a
= 12 - 5a^2 - 5a + 5 +5a
= 17 - 5a^2

x^3 + 3x^2 + 6x + 18
______
3. x-3/ x^4 + 7
- ( x^4 - 3x^3)
----------------
3x^3 + 7
- (3x^3 - 6x^2)
-------------------
6x^2 + 7
- (6x^2 - 18x)
-------------------
18x + 7
- (18x - 54)
--------------
7 + 54 = R = 61
