x = 51.98
Step-by-step explanation:
tan 68 = opp/hyp = x/21
or
x = 21×tan68°
= 21(2.475)
= 51.98
Answer:
????
Step-by-step explanation:////
We have an inscribed angle here. Angle YXZ is an inscribed angle.
Angle YXZ can also be expressed as simply angle x but I will use angle YXZ.
Angle YXZ = (1/2)(arc YZ)
Angle YXZ = (1/2)(144°)
Angle YXZ = 72°
Done!
Answer:
4pq(p³+q³)
Step-by-step explanation:
Exactly 5 game would be when 4 wins and 1 loss of a particular person
loss has to be one of the first 4 games
A wins: qp⁴ + pqp³ + p²qp² + p³qp
= qp⁴ + qp⁴ + qp⁴ + qp⁴ = 4qp⁴
B wins: pq⁴ + qpq³ + q²pq² + q³pq
= pq⁴ + pq⁴ + pq⁴ + pq⁴ = 4pq⁴
A wins or B wins:
4pq⁴ + 4qp⁴ = 4pq(q³+p³)
