There can only be one reason for that . . . making
something tough out of something easy.

<u>-19  =  x - 7</u>

How could you get 'x' all by itself on one side,
and everything else on the other side ?

What if you add  7  to each side ?

Then you have    <em> -12  =  x </em>   .  To your amazement, that's the solution !

Find the missing length indicated.<br> A) 48 <br> B) 36 <br> C) 100 <br> D) 64
alexandr402 [8]

Answer:

Option D) 64

Step-by-step explanation:  

see the attached figure with letters to better understand the problem

<em>In the right triangle BCD find BC</em>

Applying the Pythagoras Theorem

BC^{2}=48^{2}+36^{2}\\BC^{2}=3,600\\BC=60\ units

<em>In the right triangle ABC</em>

cos(C)=BC/AC

substitute the values  

cos(C)=60/(x+36) -------> equation A

<em>In the right triangle BDC</em>

cos(C)=CD/BC

substitute the values

cos(C)=36/60 -------> equation B

equate equation A and equation B

60/(x+36)=36/60\\ \\(x+36)*36=60*60\\ \\36x+1,296=3,600\\ \\36x=3,600-1,296\\ \\36x=2,304\\ \\x=64\ units

Solve for the value of k. (k+8) 400​
pashok25 [27]

Answer:

value of k = 6

Step-by-step explanation:

sum of all angles forming a straight line = 180°

so,

  • 7k + 8 + 90 + 40 = 180
  • 7k + 138 = 180
  • 7k = 180 - 138
  • 7k = 42
  • k = 42/7
  • k = 6

hence the value of k = 6
