Answer: 5/8
Step-by-step explanation: The ratio is 10:16 because total of 16 pens and 10 being red.
56°
A triangle makes a total of 180°
They have already given you the 83° and you know a line makes 180° so 180-139 gives you 41°.
83+41=124
180-124=56

Answer:
16 inches
Step-by-step explanation:
Given,
Perimeter = 72 inches
Breadth = 20 inches
Perimeter = 2 ( L+B )
72 = 2 ( L+20)
72= 2L + 40
72-40=2L
32/2=L
L=16 inches
therefore , lenght of the tile is 16 inches
