Answer:

Step-by-step explanation:

Use Pythagorean theorem

$a^2 +b^2 =c^2$

c= always hypotenuse/ longest side/ side across from right angle = 13

a= 5

$5^2+b^2=13^2$

$25+b^2=169$

Subtract 25 from 169

$b^2= 144$

Square root both sides

b= 12

--------

it's also a special triangle known as a 5, 12, 13 triangle

Liono4ka [1.6K]

Answer:

His book was opened at Page no.296 and Page no.297

Step-by-step explanation:

Let the page number of one page be x

Page number of page facing page no. x = x+1

We are given that the product of the facing pages was 87,912.

So, x(x+1)=87912

$x^2+x=87912$

$x^2+x-87912=0$

$x^2-296x+297x-87912=0$

$x(x-296)+297(x-296)=0$

(x+297)(x-296)=0

x=296,-297

Since Page no. cannot be negative

So, x=296

x+1=296+1=297

So, his book was opened at Page no.296 and Page no.297

What is the measure of Angle z?

denis-greek [22]

Answer:

Angle z makes a 180° angle when added to the angle of 124° in the first image, because they are on the same side of a straight line. Just subtract 124 from 180. =56 For the second picture, angle m will be the same as angle z because of the properties involved.

3-3x6+2 and how is that reached, please!

Dvinal [7]

The order of mathematical operation is MDAS.
M - multiplication
D - division
A - addition
S - subtraction

3 - 3 x 6 + 2

Multiplication : 3 x 6 = 18
Division: none
Addition : + 3 + 2 = 5 (combine positive numbers)
Subtraction : 5 - 18 = -13

3 - 18 + 2 = -13

Which graph best represents the solution set of 2/3x + y ≤ − 2?

DochEvi [55]

Answer:

Step-by-step explanation:

The answer is D. Easy way to tell, the less than or equal to sign indicates a solid line in the graph. Equal=solid line. Also when you solve for y, the slope of the line (-2/3)is negative, indicating a line sloping downward.
