Answer:
b = 55°
Step-by-step explanation:
The angle at the centre is twice the angle on the circle subtended by the same arc, then
a = 0.5 × 110° = 55°
Angles on the circumference subtended by the same arc are congruent, so
b = a = 55°
Answer:
D 3 3/4 and 7/10
Step-by-step explanation:
A) 2 3/8 and 3/4
4 goes into 20 evenly but 8 does not
NO
B) 1 5/6 and 2/5
5 goes into 20 evenly but 6 does not
NO
C) 4 1/3 and 1/4
4 goes into 20 evenly but 3 does not
NO
D) 3 3/4 and 7/10
4 goes into 20 evenly and 10 goes into 20 evenly
YES 3 3/4 = 3 15/20 and 7/10 = 14/20
There are a couple of ways to tackle this one, using the 45-45-90 rule or just using the pythagorean theore, let's use the pythagorean theorem.
the angle at A is 45°, and its opposite side is BC, the angle at C is 45° as well, and its opposite side is AB, well, the angles are the same, thus BC = AB.
hmmm le'ts call hmmm ohh hmmm say z, thus BC = AB = z.

A
