Hey! since it’s a 5 sided shape it’s area will be 540° so you add up 108+100+90+120=418
the final angle is 122*
then since angles on a straight line is 180° you minus 122 from 180 and x= 58°

Find the missing the side of the triangle A. 130−−−√ m B. 179−−−√ m C. 42–√ m D. 211−−−√ m

LuckyWell [14K]

Answer:

<h2>The answer is option A</h2>

Step-by-step explanation:

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

Using the Pythagoras theorem

That's

${a}^{2} = {b}^{2} + {c}^{2}$

From the question

x is the hypotenuse or the longest side of the triangle

Substituting the values into the above formula we have

${x}^{2} = {9}^{2} + {7}^{2}$

${x}^{2} = 81 + 49$

${x}^{2} = 130$

Find the square root of both sides

We have the final answer as

Hope this helps you
