Question

I need help solving for x. with pythagorean theorem.​

Answer 1

Answer:

$14 \sqrt{3}$

Step-by-step explanation:

Here you use the 30-60-90 triangle

Note that the side length opposite of the 60 degree triangle is root of 3 times greater than the side opposite of the 30 degree angle.

Here, x is the opposite of 60 degree angle.

7 times root of 4 is opposite of the 30 degree angle,

So we have

So this means

$7 \sqrt{4} \times( \sqrt{3} ) = x$

Note that

$7 \times \sqrt{4} = 7 \times 2 = 14$

So we have

$14 \sqrt{3} = x$
