Find the value of x using the measures of the two given adjacent supplementary angles. The figure is not drawn to scale.

andrey2020 [161]

Answer:

x= 42

Step-by-step explanation:

3x+ 54=180

straight angle is 180

So just solve the equation.

subtract 54 on both sides.

126=3x

divide that by 3, and you get 42.

check You answer by multiplying 42 And 3, Which basically Is 126

and then 126+54

which is then 180

I hope this Helps!

In a right triangle, the hypotenuse has endpoints P(–3, 2) and Q(1, –3). On a coordinate plane, line P Q has points (negative 3,

mrs_skeptik [129]

Answer:

The length of PR is 5 units

Step-by-step explanation:

Here, we want to calculate the length of PR

Since PQ is the hypotenuse, it means that the right-angle would be between lines PR and RQ

Also, since R is on the third quadrant, then its coordinates are (-x,-y)

To get the coordinates of R since we know that we need a right angle, we drop a straight vertical line through P and a straight horizontal line through Q

What this mean is that the coordinates of R will take the x-coordinate of the point P and the y-coordinate of the point Q

Hence, we have that the coordinates of the point R is (-3,-3)

Now, we want to calculate the length of PR

PR will be the distance between the points P and R

Mathematically, to get this, we use the distance formula

That will be;

√(y2-y1)^2 + (x2-x1)^2

Thus, we have

√(2-(-3)^2 + (-3-(-3))^2

= √5^2 + 0^2

= √25 = 5 units

Answer:

27.27%

Step-by-step explanation:

Given that,

Initial price = 11

Final price = 8

We need to find the percentage change in the price. It can be calculated as follows :

% = [(final-initial)/initial] × 100

So,

$\%=\dfrac{11-8}{11}\times 100\\\\\%=27.27\%$

So, the percentage decrease is 27.27%.

Anna baked

Hitman42 [59]

Answer:

expression for cookies Anna have 3c- 8

Step-by-step explanation:

Given:

Number of cookie batches Anna baked = 2

Number of cookies in each batch = c

Number of cookies Anna ate = 8

To Find:

An expression representing the number of cookies left with Anna

Solution:

Let the expression representing the number of cookies left with Anna be y

First let us find the total number of cookies Anna baked

She baked 3 batches of cookies and each batch had c cookies in it

So,

Total number of cookies Anna baked = number batches X Number of cookies in each batch

=> $3 \times c$

=> 3c

Now Anna ate 8 from 3c cookies, so she will be left with

=>3c-8 cookies

So , y = 3c- 8
