Answer:

12 sides

Step-by-step explanation:

If the three equal angles add to 90, this means each of those angles must by 30 degrees.

Next, we can use the theorem that the sum of the exterior angles adds to 360 (this is true for any polygon). So, as the exterior angles are all equal to 30, we just work out 360 ÷ 30 = 12.

So the polygon has 12 angles, and therefore 12 sides also.

Lelu [443]

<span>For the answer to the question above, We have a right angled triangle with an opposite of 300.5 ft. (306 - 5.5) and an adjacent of 400 ft. Recalling SOH CAH TOA, tanθ = O/A.
tan(θ) = 300.5/400.
θ = tan^-1(300.5/400).
So the answer is
θ = 36.9°.
I hope my answer helped you.</span>

Answer:

45%

Step-by-step explanation:

Simply divide your partial amount (18 in this case) by your total (40), and you then multiply your answer from 18/40= .45 by 100, and you get 45. This is 45%

Answer:

your answer is C.

Lines that are not coplanar and do not intersect are called skew lines.

and incase you need this answer too, Parallel Planes. Two planes that do not intersect are called parallel planes.

<h3>Answer: 140 degrees</h3>

==================================================

Explanation:

See the diagram below.

We start with triangle PQR with the given angles mentioned. Then you extend out segment QR to form line QR. It goes off infinitely in both directions.

The exterior angle x adds to the interior angle Q = 40 to get 180

x+40 = 180

x+40-40 = 180-40 ... subtract 40 from both sides

x = 140

The exterior angle is 140 degrees
