Answer:
Semicircle
Step-by-step explanation:
As we can see, the arc is bounded by the chord MO
since the chord passes through the center of the circle, we have it that the chord is a diameter
Mathematically, an arc bounded by a diameter represents half of a circle
So we can conclude that the arc MNO in circle C is a semicircle

Answer:
Step-by-step explanation:
Answer: the area of the triangle = 10.5 cm²
Step-by-step explanation:
Let 3x=a, 4x=b, 5x=c.
Hence,
P=2*(a+b+c)
36=2*(3x+4x+5x)
36=2*12x
36=24x
Divide both parts of the equation by 24:
1.5 cm=x
a=3x
a=3*1.5
a=4.5 cm
b=4x
b=4*1.5
b=6 cm
c=5x
c=5*1.5
c=7.5 cm
