Answer:

50 degrees

Step-by-step explanation:

You can see that angle ADC is composed of angle ADB and angle BDC

Angle ADB is 38 degrees and angle BDC is 12 degrees

Therefore angle ADC is 50 degrees

Angle ADC is opposite from angle ABC so they are congruent.

So angle ABC is 50 degrees

The length of the SM parallelogram when the length of the rectangle is 15 cm and width is 8 cm is 8/5 units.

<h3>What is the area of a rectangle?</h3>

Area of a rectangle is the product of the length of the rectangle and the width of the rectangle. It can be given as,

$A=a\times b$

Here, (a)is the length of the rectangle and (b) is the width of the rectangle

The length of the rectangle is 15 cm and width is 8 cm. Thus, the area of it is,

$A=15\times8\\A=120\rm\; cm^2$

All three parts has equal area. Thus, the area of parallelogram NCMA is,

$A_p=\dfrac{120}{3}\\A_p=40\rm\; cm^2$

MN is the height of the parallelogram. Thus,

$A_p=h\times AS\\40=h\times15\\h=\dfrac{40}{15}\\h=\dfrac{8}{5}$

Thus, the length of the Sm parallelogram when the length of the rectangle is 15 cm and width is 8 cm is 8/5 units.

How do i solve this radical expression? It has to do with factoring i know that.

MAVERICK [17]

Firstly it's not a radical expression.

You can factorize the numerator x²+12x+36 = (x+6)²

Factorize the denominator 12x+72 = 12(x+6)

=(x+6)² / 12(x+6) , simplify. Answer = (x+6)/12

16. write an inequality for each graph

Harrizon [31]

Answer:

Question 16

(a) x < 1 : the values of x are smaller than than 1 (e.g. possible values are 0, -1, -2, etc) and since the circle is not shaded it means that 1 isn't a possible value of x

(b) x $\geq$ -2 : the circle is filled therefore -2 is included in the answer

Question 17

(a) unfilled dot above -2 and arrow pointing to the left

(b) shaded circle above 4 with and arrow pointing to the right →
