Which relationship describes angles 1 and 2

First option and Third option

Step-by-step explanation:

You can observe in the figure that the angle 1 and the angle 2 have a common vertex and a common side. These kind of angles are known as "adjacent angles".

You can observe that the intersection of the lines forms four equal anles wich are right angles (Angles of 90 degrees). Thererefore, the angles 1 and 2 and also "complementary angles", because the sum of them is 90 degrees.

Then, the answers are the first option and the third option.

answer is x<

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.
