Just plug in the numbers:
4: 16 + 24 = 40 YES
5 = 25 + 40 ≠ 40 NO
8: 64 + 48 ≠ 40 NO
10: 100 + 60 ≠ 40 NO
So A. is the correct answer. Just to be sure:
-10: 100 + ( - 60) = 40
Your answer is A. Hope that helps! :)
Answer:
x = 21
Step-by-step explanation:
Inscribed angle = (3x - 3)°
Intercepted arc measure = 120°
Thus:
(3x - 3)° = ½(120°) => an inscribed angle of any circle = ½ the measure of its intercepted arc.
Multiply both sides by 2
2(3x - 3) = 120
6x - 6 = 120
6x - 6 + 6 = 120 + 6
6x = 126
6x/6 = 126/6
x = 21
To find the angle of vertex E,we need to first find the sum of interior polygons to determine x:
In this case,the equation would be:
(7-2)×180°
=5×180°
=900°
We can then find the value of x:
(4)6x+(2)2x+8x=900°
24x+4x+8x=900°
36x=900°
x=25°
The interior angle of vertex E:
6x=6(25)=150°
Therefore,the interior angle of vertex E is 150°.
Hope it helps!
