Answer:
b ≈ 7.54 cm
Step-by-step explanation:
Pythagorean Theorem
a² + b² = c²
a and b are the sides and c is the hypotenuse
hypotenuse is 11 cm
a side is 8 cm
so
8² + b² = 11²
64 + b² = 121
-64 -64
b² = 57
√b² = √57
b ≈ 7.54 cm ( use ≈ because its rounded so its not exact)
10:14, 15:21, 20,28
All you need to do when finding equal ratios is multiply both sides by the same number, In this case you could multiply both sides by 2 and get 10:14 or multiply both sides by 10 and get 50:70. The concept is quite easy.
