Answer:
1) Missing Length: 20 m
Equation:
2) Missing Length: 100√5 mm
Equation:
Step-by-step explanation:
1) We can use Pythagorean Theorem to solve this triangle and find the length of the hypotenuse.
Luckily, 400 is a perfect square :)
So, the length of the hypotenuse is 20 cm.
2) Again, we can use the Pythagorean Theorem to find the missing length.
But, we can still simplify the radical.
So, the length of the missing length is 100√5 cm.
