9 / 15
9 / 3 = 3
15 / 3 = 5
so 3 / 5
60/100
6/10
2/5 = (2x2)/(5x2) = 4/10 = 0.4
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
So it must have side length √16 = 4 cm and diagonal length 4√2 cm.
