a)
Some triangles have three right angles.
b)
Some triangles have no acute angles.
c)
Some triangles have one obtuse angle and two acute angles.

Step-by-step explanation:

a) false:because sum of acute angles in a triangle is 90

b) false;because no triangle cannot have an acute angle

c) true;because sum of angles in a triangle is equal to two acute angle

show us the graphs dude

step-by-step explanation:

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
