If EG=67, then EF=?<br> There is a picture below
ikadub [295]
If EG=67 we have (3x+7)+(5x-4)=67
let's simplify
67 = (3x + 7) + (5x - 4) \\ 67 = 8x + 3 \\ 64 = 8x \\  \frac{64}{8}  = x \\ 8 = x
now we know x is 8 we can use this to find EF
since EF=3x+7
3(8) + 7 = 24 + 7 = 31
so we have EF is 31!

Find the value of x. A. 53–√ m B. 241−−√ m C. 6 m D. 6+35–√ m
dalvyx [7]

Answer:

<h2>x = 2√41 m</h2>

Step-by-step explanation:

Since the triangle is a right angled triangle we can use Pythagoras theorem to find the missing side x

Using Pythagoras theorem we have

a² = b² + c²

where a is the hypotenuse

From the question x is the hypotenuse

So we have

<h2>{x}^{2}  =  {8}^{2}  +  {10}^{2}</h2><h2 /><h2>{x}^{2}  = 64 + 100</h2><h2 /><h2>{x}^{2}  = 164</h2>

Find the square root of both sides

We have the final answer as

<h3>x = 2√41 m</h3>

Hope this helps you
