Answer:

585°

Step-by-step explanation:

To convert from radians to degrees

• degree measure = radian measure × $\frac{180}{\pi }$ , hence

degree measure = $\frac{13\pi }{4}$ × $\frac{180}{\pi }$

Cancel the π on the numerator/denominator

= $\frac{13(180)}{4}$ = 585°

Answer:

585°

Step-by-step explanation:

2 π = 360° = 180/pi

(13pi/4) x (180/pi)

(13/4) x (180/1)

(13/1) x (45/1)

585°

Answer: x= 2.5, y = 10

Step-by-step explanation:

<u><em>I'm going to assume that these photocopies are proportional in relations to each other.</em></u>

If they're proportional, you can set up two proportions:

$1) \frac{x}{5} =\frac{3}{6} \\\\2) \frac{5}{y} =\frac{3}{6}$

And cross-multiply:

$1) 6x = 5*3 \\\\2) 3y = 5*6$

Then solved for x and y:

$1) 6x = 15\\x=\frac{15}{6} =\frac{5}{2} =2.5 \\\\2) 3y = 30\\y=\frac{30}{3} =10$

The measure of the supplement of an angle is 84° less than the measure of the angle. Find the measures of the angles

babunello [35]

Let the measure of angle be 'x'

Since, the measure of the supplement of an angle is 84° less than the measure of the angle.

Therefore, measure of supplement of x = x - 84°

The measure of two supplementary angles is 180 degrees.

$x + x -84^\circ = 180^\circ$

$2x -84^\circ = 180^\circ$

$2x =84^\circ + 180^\circ$

$2x =264^\circ$

$x =132^\circ$

So, the measure of angle = $x =132^\circ$

Its supplement = x - 84° = 132° - 84°

= 48°

So, the measure of supplement of angle is 48 degrees.
