a² + b² = c²
c² = 19² + 34²
c² = 1517
c = √1517
c = 38.95 units.
Find missing angle A:
Find Missing B:
Answer: Missing length = 38.95 units ; Missing angles = 29.2° and 60.8°
Answer: The piano has 222 strings, because 37×6=222.
Step-by-step explanation:
Since we are informed that Leslie tuned a guitar with 6 strings today and that she then tuned a piano with 37 times as many strings.
This simply means that we have to multiply 37 by 6 strings to get the value of the strings of the piano that she tuned. This will be:
= 6 × 37
= 222 strings.
Leslie tuned 222 strings.
Therefore, the piano has 222 strings, because 37×6=222.
