Answer:
Arc AC = 90°
Step-by-step explanation:
Postulate:
The measure of an arc will ALWAYS be equal to the measure of the central angle of the circle.
The angle of arc AC is marked with a square.
That square mark means it is 90°.
So the arc would also measure 90°.

Answer:
1/19( -171 - 10√5 + 40√30)
Step-by-step explanation:
Probably the best way to do this would be to mutiply each fraction ( top and bottom) by the conjugate of the denominator. This would then give a denominator with no radicals.
So 2√5 / √6 + 5 wil be multiplied by (5 - √6) / (5 - √6)) to give
(10√5 - 2√30)/ (25 - 6).
= 2√5 (5 - √6) / 19
Do the same with th other 2 fractions and the simplifuication will be a lot easier.
I did this and got 1/19( -171 - 10√5 + 40√30)
Step-by-step explanation:
-1/ 4 , -2/4 , 0.20 , 0.90 ,3/4 ,1.50 - 0.50 ,7/4
because if you changed them whole to decimal it shows the result
-1/4 = - 0.25
-2 / 4 = - 0.5
3 / 4 = 0.75
1.50 - 0.50 = 1
7/4= 1.75
0.20 and 0.90 are already decimal numbers
