Find the missing side b in a right triangle where a=8 and c=18

1 answer:

4 0

Using Pythagorean theorem c^2=a^2 + b^2, we can find the missing side b.
Put values in equation.
18^2 = 8^2 + b^2
324=64+b^2
Subtract 64 from both sides
260= b^2
Take square root.
2√65=b
or
b=16.12

Answer: b=2√65 Radical form. or b=16.12 Decimal form.

AB and DE are chords that intersect at point F inside circle C as shown. If the measure of arc EA= 50 degrees and the measure of

defon

Answer:

Part 1) $m\angle AFE=55^o$

Part 2) $m\angle EFB=125^o$

Step-by-step explanation:

Part 1) what is the measure of angle AFE

we know that

The measure of the interior angle is the semisum of the arches that comprise it and its opposite.

Note: In this problem the correct measure of arc EA is 40 degrees (see the picture)

$m\angle AFE=\frac{1}{2}(arc\ EA+arc\ DB)$

substitute the given values

$m\angle AFE=\frac{1}{2}(40^o+70^o)=55^o$

Part 2) what is the measure of angle EFB?

we know that

$m\angle AFE+m\angle EFB=180^o$ ---> by supplementary angles (form a linear pair)

substitute the given value

$55^o+m\angle EFB=180^o$

$m\angle EFB=180^o-55^o=125^o$

6. Find the equation in slope-intercept form for the line that passes through the point (-8, 3) and is parallel

prisoha [69]

<h3>The equation in slope-intercept form for the line that passes through the point (-8, 3) and is parallel to the line -5x + 4y = 8 is:</h3>

$y = \frac{5}{4}x + 13$

Solution:

Given that,

We have to find the equation in slope-intercept form for the line that passes through the point (-8, 3) and is parallel to the line -5x + 4y = 8

The equation of line in slope intercept form is given as:

y = mx + c

Where "m" is the slope of line

From given,

-5x + 4y = 8

Rearrange to slope intercept form

4y = 5x + 8

$y = \frac{5x}{4} + \frac{8}{4}\\\\y = \frac{5x}{4} + 2$

On comparing the above equation with slope intercept form,

$m = \frac{5}{4}$

We know that, slopes of parallel lines are equal

Therefore, slope of line parallel to the line -5x + 4y = 8 is:

$m = \frac{5}{4}$

$\text{Substitute } m = \frac{5}{4}\ and\ (x, y) = (-8, 3) \text{ in eqn 1}$

$3 = \frac{5}{4} \times -8 + c\\\\3 = -10 + c\\\\c = 13$

Substitute c = 13 and m = 5/4 in eqn 1

$y = \frac{5}{4}x + 13$

Thus the equation of line in slope intercept form is found

What is the slope of the line shown?

Mekhanik [1.2K]

Answer:

1/2

Step-by-step explanation:

basically just remember the basic rise over run!

the y intercept is -3 the rise is one and to run over the next exact point is 2
