Chapter 78, Problem 1A

To determine

To show:

The right triangle that contains the angle T.

To show:

The right triangle that contains the given angles.

Explanation of Solution

Given information:

A diagram with top view, front view and size view has given.

  

  Calculation:

Rectangular solid form by the given blocks.

  

Top view, front view and side view are given for the solid pyramid. When these blocks are combined with each other than that form a rectangular solid, which contain angle R and angle T with some right angles.

Here angle MBO is right angle which is formed by top view.

Angle OBN is right angle which is formed by side view.

Angle R is formed at right-angle triangle MNB andright-angle triangle ONB in which angles are given.

Angle T is formed atright angle triangleBMO and right-angle triangle BMO.
