<h2>
Answer:</h2>
For ∠1: Because all angles inside a triangle equal 180°, set ∠2, 68, and ∠1 equal to 180, then solve for ∠1.
∠1 = 63°
For ∠3: Subtract 93 from 180 to get ∠3
∠3 = 87°
For ∠4: Because all angles inside a triangle equal 180°, set ∠3, 49, and ∠4 equal to 180, then solve for ∠4.

</h2>
∠4 = 44°
∠2 = 49°
Answer:
25π cm ≈ 78.54 cm
Step-by-step explanation:
The diameter of the circumscribing circle is the diagonal of the rectangle.
You may recognize the rectangle dimensions as the numbers in the (7, 24, 25) Pythagorean triple. If not, you can compute the diagonal length from ...
d = √(7²+24²) = √(49+576) = √625 = 25 . . . . centimeters
The circumference of the circle is π times the diameter:
C = πd = 25π cm
Answer:
P(A)=0.55
P(A and B)=P(A∩B)=0.1265
P(A or B)=P(A∪B)=0.7635
P(A|B)=0.3721
Step-by-step explanation:
P(A')=0.45
P(A)=1-0.45=0.55
P(B∩A)=?
P(B|A)=0.23
P(B|A)=(P(A∩B))/P(A)
0.23=(P(A∩B))/0.55
P(A∩B)=0.23×0.55=0.1265
P(A∪B)=P(A)+P(B)-P(A∩B)
=0.55+0.34-0.1265
=0.7635
P(A|B)=[P(A∩B)]/P(B)=0.1265/0.34 ≈0.3721
Lol the first answer the pic is so funny
