Answer:the measure of angle B is A
Step-by-step explanation:42 is the angle of A and C together so it is the same on the other side
4n - 3 = 4 * 10 - 3 = 40 - 3 = 37
....
Answer:
(a)No. The probability of drawing a specific second card depends on the identity of the first card.
(b)4/663
(c) 4/663
(d) 8/663
Step-by-step explanation:
(a)The events are not independent because we are drawing cards without replacement and the probability of drawing a specific second card depends on the identity of the first card.
(b) P(ace on 1st card and jack on 2nd).

(c)P(jack on 1st card and ace on 2nd)

(d)Probability of drawing an ace and a jack in either order.
We can either draw an ace first, jack second or jack first, ace second.
Therefore:
P(drawing an ace and a jack in either order) =P(AJ)+(JA)
From parts (b) and (c) above:

Answer:
= 52°
Step-by-step explanation:
The obtuse angle at O is twice the angle made at the circumference /by the same segment b.
=52×2=104°
The base angles that are made by isosceles triangle that has the apex with angle 104° equal to (180-104)/2=38°
The radii of a circle are equal and meet tangents at right angles.
Angle a= 90-38= 52°
The angles are congruent because they are vertical so we can set them equal to one another.
3x + 50 = 6x - 10
3x + 60 = 6x
60 = 3x
20 = x
