8:9 cannot be simplified any further, so you need to multiply both sides of the ratio with a same integer. Let's multiply them by 2:

8*2 : 9*2

16 : 18.

That is one equivalent ratio of 8:9.

Triangle JKL is fromed by plotting three points. What is the leanth of sides JK?

Phoenix [80]

<h3><u>Solution</u><u>:</u><u>-</u></h3>

J (1,5)
K (1,9)

$\LARGE\leadsto\sf JK=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$\LARGE\leadsto\sf \sqrt {(1-1)^2+(9-5)^2}$

$\LARGE\leadsto\sf \sqrt {(0)^2+(4)^2}$

$\LARGE\leadsto\sf \sqrt {0+16}$

$\LARGE\leadsto\sf \sqrt {16}$

$\LARGE\leadsto\sf JK=4units$

From the triangle below, if AD = 5 and CD = 20, find the length of side BD.

krek1111 [17]

The length of side BD, given that AD = 5 and CD = 20 is 10 (Option A)

<h3>Data obtained from the question</h3>

Length of side AD = 5
Length of side CD = 20
Length of side BD =?

<h3>How to determine the length of side BD</h3>

Since the triangles are similar, we can obtain the length of side BD as illustrated below:

CD / BD = BD / AD

20 / BD = BD / 5

Cross multiply

BD × BD = 20 × 5

BD² = 100

Take the square root of both sides

BD = √100

BD = 10

Thus, the length of side BD is 10
