These triangles are not congruent. They only have 2 sides and one angle in common, and that is not a congruency theorem.
You take the number of the colored pencils and divides it with the people in the class.
350/14 = 25
34
because, 34 = 14 + (10 x 2)
and 34 = 24 + (10 x 1)
Answer:
8.75cm²
Step-by-step explanation:
First we need to find the angle subtended by the arc
L = theta/360 * 2pir
3.5 = theta/360 * 2*3.14(5)
3.5 = theta/360 * 31.4
theta/360 = 3.5/31.4
theta/360 = 0.11146
theta = 0.11146 * 360
theta = 40.13 degrees
Area of the sector = theta/360 * pir^2
Area of the sector = 40.13/360 * 3.14*25
Area of the sector = 40.13/360 * 78.5
Area of the sector = 8.75cm
Hence the area of the sector is 8.75cm²
