Answer: 20°, 50° and 90°

Step-by-step explanation:

From the question, we are informed that the measures of the three angles whose sum is 160 are in the extended ratio ​2:​5:9.

The exact angle measures will then be:

= 2/(2+5+9) × 160°

= 2/16 × 160°

= 20°

= 5/(2+5+9) × 160°

= 5/16 × 160°

= 50°

= 9/(2+5+9) × 160°

= 9/16 × 160°

= 90°

MAVERICK [17]

Answer:

The answer to your question is below

Step-by-step explanation:

1.- Find the volume of the cylinder

Data

diameter = 9 cm

radius = 4.5 cm

height = 15 cm

Formula

   V = πr²h

   V = π(4.5)²(15)

  V = 303.75π         This is te answer for the volume in terms of π

       = 952.78 cm³                

2.- Find the volume of the cylinder

height = 40 yd

radius = 12 yd

Formula

   V = πr²h

   V = π(12)²(40)

   V = 5760π              This is te answer for the volume in terms of π

       = 18086.4 cm³

3.- What is the height .......

height = q

side length = r

4.- Volume of a pyramid

    Volume = Area of the base x height

Area of the base = 11 x 11 = 121 cm²

    Volume = 121 x 18

   Volume = 2178 cm³
