Answer:
Step-by-step explanation:
The angles form a straight angle, and thus add to 90 degrees.
Step-by-step explanation:
Head(H) Tails(T)
Sample space is S (HHH,HHT,HTH,THH)
Event(HHT,HTH,THH)
so the probability is 3/4
Answer:
Bk = 65
Step-by-step explanation:
BK as we can see is 4x + 1
If two triangles are similar, the ratio of the corresponding sides are the same
Thus;
2x+7/27 = 4x + 1/45
45(2x + 7) = 27(4x + 1)
90x + 315 = 108x + 27
108x-90x = 315-27
18x = 288
x = 288/18
x = 16
From the question;
BK = 4x + 1
BK = 4(16) + 1
BK = 64 + 1
BK = 65
