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>

</h2><h2 /><h2>

</h2><h2 /><h2>

</h2>
Find the square root of both sides
We have the final answer as
<h3>x = 2√41 m</h3>

Answer:
y=-7/2x+10
Step-by-step explanation:
7x+2y=20
2y=20-7x
2y=-7x+20
y=-7/2x+20/2
y=-7/2x+10
69 and 83 hundredths
69.83 is the answer
