Angle 1 is 3 times angle 2. Find angle 2

Mathematics

Angle 2 is 40 degrees

Explanation:
A straight line is always 180 degrees, they gave us 160 degrees so you just subtract 180-160 to get 20 degrees for angle 3.

Since that angle is a part of the triangle and we’re only focusing on angles 1 and 2, subtract 20 from 180 since a triangle is 180 degrees.

Then you get 160, divide that by 4 to get 40 degrees, multiply 40 by 3 to get angle 1 which is 120. 120+20 (20 from angle 3) gives us 140. 180-140 is 40 degrees which is angle 2.

soln,

here area of base = 25/4 unit ^ 2

height of the prism = 8/5 unit

so,

volume of prism = area of base x height of the prism

=  \frac{25}{4}  \times  \frac{8}{5}

= 10 \:  \:  {unit}^{2}

so the volume of the prism is 10 unit^2
