4x + 2x = < y

This is because the opposite sides (which is 4x and 2x) of a triangle add up to the exterior angle (<y).

We have to find X.

As you know:

3x + 4x + 2x = 180

because the angles of a triangle add up to 180.

When we add them:

9x = 180

x =  \frac{180}{9}

The 9 is multiplying with the X. We want X only and not 9 with it. So, when we take 9 to the other side, it becomes divide. As a result, the answer to x is:-

x = 20

Substitute value of x into 4x and 2x to find the exterior angle:-

4x:

4(20) = 80

2x:

2(20) = 40

When we add them we get the answer for angle Y:-

80 + 40 = 120

Therefore, we can conclude that:

< y = 120 \: degrees

Find the volume of each three dimensional figure (3 problems please help)
grin007 [14]

Answer:

Step-by-step explanation:

1) The solid is a cube. The formula for determining the volume of a cube is expressed as

Volume = s³

s = 5 cm

Therefore,

Volume = 5³ = 125 cm³

2) The solid is a cuboid. The formula for determining the volume of a cuboid is expressed as

Volume = lwh

l = 10 inches

w = 5 inches

h = 2 inches

Therefore,

Volume = 10 × 5 × 2 = 100 inches³

3) The solid is a square base pyramid. The formula for determining the volume of a square base pyramid is expressed as

Volume = Area of square base × height

Area of square base = 3² = 9 m²

h = 10 m

Volume = 9 × 10 = 90m³
