Answer:

$14.16\\15. a) 14$

Step-by-step explanation:

$14. We\ are\ given\ that,\\The\ assumed\ number\ x\ is\ 4\ more\ than\ 12\\Hence,\\x=4+12\\x=16\\Lets\ see\ that\ x=16\ as\ a\ solution,\ matches\ with\ the\ other\ information\ provided.\\We\ are\ also\ given\ that,\\x13, 16\ is\ greater\ than\ 13\ too.\\x$

$15. a)\\Let\ the\ assumed\ no.\ be\ y\\Here,\ we\ are\ given\ the\ following\ information\ about\ y:\\y>10,\\y12\\y13,\\y=14$

Some isosceles triangles are not equilateral.<br> O A. True<br> O B. False

Sergeu [11.5K]

I looked it up, it says eq triangles have 3 sides. An isos triangle is one with 2 equal sides. Every eq triangle is isos, but not every isos triangle is equilateral. I think the statement in the photo is true.

Prove the identity cos(x-y)-cos(x+y)=2sinxsiny

tekilochka [14]

Answer:

see the procedure

Step-by-step explanation:

we know that

$cos(X - Y) = cosX cosY + sinX sinY\\cos(X + Y) = cosX cosY - sinX sinY$

$cos(X - Y)-cos(X + Y)=cosX cosY + sinX sinY-(cosX cosY - sinX sinY)$

$cos(X - Y)-cos(X + Y)=cosX cosY + sinX sinY-cosX cosY + sinX sinY$

$cos(X - Y)-cos(X + Y)=sinX sinY+ sinX sinY$

$cos(X - Y)-cos(X + Y)=2sinX sinY$ ----> is verified

Question on picture. Please help

Elden [556K]

A rhombus is quadrilateral where all 4 sides are of equal length. Thus

5x + 2 = 2x + 12

3x = 10

x = 10/3

substituting x into either expression, yields

56/3

therefore side AB = 56/3
