Question

find the value of x.
find the missing length.

Answer 1

Ответ:

2]. 8; 4]. 48.

Объяснение:

2. Two triangles, ΔMNL~ΔFGL,

then it is possible to make up the next proportion:

MN/FG=NL/GL=ML/FL;

after substitution:

$\frac{35}{28} =\frac{30}{24} =\frac{6x-8}{32}; \ = > \ \frac{6x-8}{32} =\frac{5}{4};\\\\6x-8=40; \ x=8.$

finally, x=8.

4. in this triangle ratio is 64:x=x:36, then

$\frac{64}{x} =\frac{x}{36} ; \ = > \ x^2=64*36; \ = > \ x=\sqrt{64*36} =6*8=48.$

finally, x=48.
