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.
Answer:
(C)only line u and line v
Step-by-step explanation:
To verify this, the easiest route is using corresponding angles.
See the attached image for the missing angles which we use for the comparison.
The angle at t which is supposed to correspond to 89 degrees on s is 91 degrees. <u>Therefore Line t is not parallel.</u>
Line u and v is parallel because the angle at u corresponds to the angle at t.
<u>Therefore, the correct option is C.</u>
A. rational.
b. irrational
c. irrational
d. rational
