Question

I WILL MARK BRAINIEST PLEASE HELP ASAP ITS DUE

Answer 1

Answer:

A) 1 : 4

B) 1 : 2

C) Base of M = 10 units

Step-by-step explanation:

A)

The ratio of the area of triangle M to triangle N

$\frac {40}{160}= \frac{1}{4} = 1 : 4$

B)

The ratio of the side lengths of triangle M to triangle N

$\sqrt{ \frac {40}{160}} = \sqrt{\frac{1}{4}} \\\\={\frac{1}{2}} \\\\=1 : 2$

C) Let the base of triangle M be b units.

$\sqrt{ \frac {40}{160}} = \frac{b}{20}\\\\\frac{1}{2}= \frac{b}{20}\\\\2b = 20\\\\b = \frac{20}{2} \\\\b = 10$
