Answer:
x+63 = 90
x = 27
Step-by-step explanation:
The two angles are complementary, so they add to 90 degrees
x+63 = 90
Subtract 63 from each side
x+63-63 = 90-63
x = 27
Answer: the total length of the string is 9 meters.
Step-by-step explanation:
The total number of strings that Emily measured is 3.
The length of the first piece of string measures 642 cm.
The length of the second piece of string measures 124 cm.
The length of the third piece of string measures 134 cm.
Therefore, the total length of the 3 pieces of string would be
642 + 124 + 134 = 900 cm.
100 cm = 1 m,
Converting 900 centimeters to meters, it becomes
900/1100 = 9 meters
