Answer:
15°
Step-by-step explanation:
sum of exterior angles=360°
each angle=360/24=15°
b
20 ×n=360
n=360/20=18
18 sides
c.
(n-2)×180=174n
180n-174n=360
6 n=360
n=360/6=60
number of sides =60
Answer:
Step-by-step explanation:
we know that
An isosceles triangle has two equal sides and two equal interior angles
In this problem
Triangle CDE is an isosceles triangle
because
EC ≅ DE
therefore
----> equation A
Remember that
The sum of the interior angles in any triangle must be equal to 180 degrees
so
----> equation B
---> equation C
substitute equation A and equation C in equation B

Answer:
8.24 is not a rational number
Step-by-step explanation:
The simple way to remember or find if the number is rational or not is that
* Rational numbers are always in the form of p/q and q should not be equal to zero
here u can even see 8.24 can be written as 8.24/0 so it is clearly showing that it is not a rational number
