Answer:
90°
Step-by-step explanation:
Arc a subtends and angle of 45° to the circumference of the circle
We know that;
An angle subtended by an arc to the center of a circle is twice the angle subtended by the same chord to the center of the circle.
Therefore, if arc a subtends and angle of 45° to the circumference of the circle then;
a will be = 45 × 2
= 90°
1)a^7/a^4
=a^[7-4]
=a³
2) r²s⁴t/r²st³
=s⁴-¹.t¹-³
=s³.t-²
=s³/t²
3)3x^6/18x
=x^5/6
Answer:
You can buy 6 tickets.
Step-by-step explanation:
21.8 + 26.6 = 48.4
48.4 x 2.50 = 121
121 / 17.50 = 6.914
Since we can't round here because it's items you're buying, we round down to the nearest flat number, which in this case is 6.
