Sam has 2 brothers. His brothers are 5 cm shorter and 7 cm shorter than him. Sam's height is 140 cm. What is the median height o
pochemuha

Answer:

The median height of Sam and his brothers is 135.

Step-by-step explanation:

First, let's find the age of Sam's brothers:

B_{1} = 140 cm - 5 cm = 135 cm

B_{2} = 140 cm - 7 cm = 133 cm

The median height of Sam and his brothers is given by the middle number of the three values arranged from lowest to highest:

133   <u>135</u>   140                      

<em>Since the middle number is 135, then the median height is 135. </em>

Therefore, the median height of Sam and his brothers is 135.

I hope it helps you!

Need help ASAP!! Write an informal proof to show triangles ABC and DEF are similar.
yaroslaw [1]

Answer:

Δ ABC and Δ DEF are similar because their corresponding sides are proportional

Step-by-step explanation:

Two triangles are similar if their corresponding sides are proportional which means the corresponding sides have equal ratios

In the two triangles ABC and DEF

∵ AB = 4 units

∵ DE = 2 units

∴ \frac{AB}{DE}=\frac{4}{2}=2

∵ BC = 6 units

∵ EF = 3 units

∴ \frac{BC}{EF}=\frac{6}{3}=2

∵ CA = 2 units

∵ FD = 1 units

∴ \frac{CA}{FD}=\frac{2}{1}=2

∴ \frac{AB}{DE}=\frac{BC}{EF}=\frac{CA}{FD}=2

∵ All the ratios of the corresponding sides are equal

∴ The corresponding sides of the two triangles are proportional

∴ Δ ABC is similar to Δ DEF
