The exterior and an interior angles always add up to 180 degrees.
180-150=One exterior angle
180-150=30
We know that all of the exterior angles add up to 360
360/30= the number of sides
360/30=12
The shape has 12 sides.
Step-by-step explanation:
distance walked by him = 1/ 3 miles
time taken in doing so = 3/ 4 hrs.


None of the triangles listed has two equal base angles or two equal side lengths, therefore: D. No triangle is isosceles.
<h3>Properties of an Isosceles Triangle</h3>
- An isosceles triangle has two base angles having equal angle measure.
- The side lengths that are opposite each of the equal base angles are also congruent to each other.
Thus, none of the triangles listed has two equal base angles or two equal side lengths, therefore: D. No triangle is isosceles.

Answer:
∴Given Δ ABC is not a right-angle triangle
a= AB = √45 = 3√5
b = BC = 12
c = AC = √45 = 3√5
Step-by-step explanation:
Given vertices are A(3,3) and B(6,9)

AB = 
Given vertices are B(6,9) and C( 6,-3)
= 
BC = 12
Given vertices are A(3,3) and C( 6,-3)

AC² = AB²+BC²
45 = 45+144
45 ≠ 189
∴Given Δ ABC is not a right angle triangle
The rectangular prism is 187.5 - 125 = 62.5 cu.inches greater than the volume of cube.
<h3>What is Volume?</h3>
Volume is defined as the space occupied by a three dimensional figure.
It is given that
A cube's edge lengths are each 5 inches
A rectangular prism's length and width are also 5 inches, but its height is 
The volume of the cube is given by side * side * side
Volume of cube = 5 *5 * 5 = 125 cu. inches
The volume of cuboid = length * width * height
<h3>Volume of Cuboid = 5 * 5 * 15/2</h3>
Volume of Cuboid = 187.5 cu.inches.
Therefore the rectangular prism is 187.5 - 125 = 62.5 cu.inches greater than the volume of cube.
