90 x 10 = 900 is the correct answer
I need help on that as well
Answer:
1980°
152.3°
3780°
164.35°
180°
360°
Step-by-step explanation:
The sum of all the interior angles of a polygon is given by (n - 2)180° where n is the number of sides.
So, the sum of all interior angles of a 13-gon is (13 - 2) 180° = 1980° (Answer)
As the 13-gon is regular, so each angles will be same. Assume each angle is x°.
So, 13x = 1980, ⇒ x = 152.3° (Answer)
Now, the sum of all interior angles for a 23-gon will be (23 - 2) 180° = 3780° (Answer)
Again,as the 23-gon is regular, so each angles will be same. Assume each angle is x°.
So, 23x = 3780, ⇒ x = 164.35° (Answer)
The sum of all the interior angles of a triangle is 180° (Answer)
The sum of all the interior angles of a quadrilateral is 360° (Answer)
The similarity between a square and a rhombus is all the sides of both are same and the difference, between a square and a rhombus is that a square has every angle 90°, but the rhombus has no angle equal to 90°. (Answer)

Answer:
MV = 160 (and %50 sure) X = 27
Step-by-step explanation:
To find MV we just have to subtract the two lengths of the perimeter that we do know, minus the total perimeter, and find the difference. (using that its, 605-160-285 = 160) with that knowledge, we can say two things. MV = 160, and <V = <T by the two side lengths being congruent. With that, we can say that X + X +X+99 = 180, and then just find X, 27+27+27+99=180.
