Answer:

if thisa is a triangle then 180-30+30 = 120 degree and we say all angles on a triangle add up to 180

Then reaply the rule changing 180 to 360 on all 4 sided shapes

180(n-2) to all other shapes.

ie) pentagon 180(n-2) = 540

continue with 540-30-30 = 480 etc....

Traveling at 65 mph how many feet can you travel in 22 minutes?

baherus [9]

If you are travelling at 65 mph, you have to think of it as if you are moving at a constant speed. By dividing 65 by 60, you are calculating how many miles you are moving each minute. In doing so, you can calculate that you are moving at 1.083333 miles each minute. That's approximately 5720 feet per minute. (This is calculated by multiplying 1.083333 by 5280 (the number of feet in a mile)). 5720 x 22 minutes, you will have traveled 125,840 feet.

Hope this helps!

Proving Angles Congruent: Find the value of x. (5x+15) degrees = (6x-10) degrees

Andrew [12]

Answer:

25 = x

Step-by-step explanation:

If the angles are congruent, they are equal

5x+15 = 6x-10

Subtract 5x from each side

5x+15 -5x = 6x-5x-10

15 = x-10

Add 10 to each side

15+10 = x-10+10

25 = x

How to solve x+9/5=5/3-x-3/6

Schach [20]

Answer:

x = $-\frac{19}{60}$

Step-by-step explanation:

$x + \frac{9}{5} = \frac{5}{3} - x -\frac{3}{6} \\x + x = \frac{5}{3} -\frac{3}{6} - \frac{9}{5} \\2x = \frac{50 - 15 - 54}{30} \\2x = \frac{-19}{30} \\x= \frac{-19}{30} / 2 = \frac{-19}{30} * \frac{1}{2} \\x= \frac{-19}{60}$
