I need to find the value of x and the measure of the exterior angle

adell [148]

Given:

In a right angle triangle, the measure of exterior angle is $(9x+16)^\circ$ .

The measure of opposite interior angle is $(5x-14)^\circ$ .

To find:

The value of x.

Solution:

Exterior angle theorem: In a triangle the measure of an exterior angle is equal to the measure of sum of two interior angles.

Using exterior angle theorem, we get

$(9x+16)^\circ=90^\circ+(5x-14)^\circ$

$(9x+16)^\circ=(5x+76)^\circ$

$9x+16=5x+76$

Isolate the variable x.

$9x-5x=-16+76$

$4x=60$

$x=\dfrac{60}{4}$

$x=15$

The value of x is 15. So, the measure of the exterior angle is:

$(9x+16)^\circ=(9(15)+16)^\circ$

$(9x+16)^\circ=(135+16)^\circ$

$(9x+16)^\circ=151^\circ$

Therefore, the value of x is 15 and the measure of the exterior angle is 151 degrees.

What is the distance in units from (2, - 12) to (-11, - 12) on the coordinate place?

mezya [45]

Answer:

B: 13

Step-by-step explanation:

we are given two points as

(2, - 12) and (-11, - 12)

so,

$x_1=2,y_1=-12$

$x_2=-11,y_2=-12$

now, we can use distance formula

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

now, we can plug values

$d=\sqrt{(-11-2)^2+(-12+12)^2}$

$d=\sqrt{(-11-2)^2+0}$

$d=13$

So,

The distance is 13

Simplification (x and ÷)

Dmitry_Shevchenko [17]

Answer:

the first answer is a⁴ +am²

Step-by-step explanation:

when dividing exponents add or subtract each other

a² + a² = a⁴

am + am =am ² ( they each have one so they add up to two)

an and mn cancel each other out

I hope this is what you need.

Answer/Step-by-step explanation:

Given:

Bracelets - $3

Necklaces - $6

To Find:

Complete the patterns in the first two columns for the cost of 0,1,2,3 and 4 pieces of jewelry. Write the ordered pair for the corresponding terms in the third column. Then graph the ordered pairs.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Solve: Complete the patterns in the first two columns for the cost of 0,1,2,3 and 4 pieces of jewelry.

Bracelets: Necklaces:

0 = $0 0 = $0

1= $3 1 = $6

2=$6 2 = $12

3=$9 3 = $18

4=$12 4 = $24

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Solve: Write the ordered pair for the corresponding terms in the third column.

Ordered Pair -

Two numbers written in a certain order.

Usually written in parentheses like this:

(12,13)

Where they cross over is the "0" point,

we measure everything from there.

The X Axis runs horizontally through zero

The Y Axis runs vertically through zero

(x, y )

Since it asking for Write the ordered pair for the corresponding terms in the third column.

Thus,

- Number of jewelry to cost -

we have:

Bracelets ⇒ ( 3, 9)

Necklaces ⇒ (3, 18)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Then graph the ordered pairs.
