What is difference between 1st angle and 3rd angle projection?

Both third angle and first angle projection display the standard three orthographic views of a part or assembly on a drawing.. The key difference between third angle and first angle is the layout of the part on the sheet.


What is the disadvantage of using isometric drawings?

One disadvantage of using isometric drawings is that they can sometimes distort the true dimensions of an object, making it challenging to accurately represent the size and proportions of the object. Additionally, isometric drawings can be more complex to create compared to other types of technical drawings, such as orthographic projections. Lastly, isometric drawings may not always provide all the necessary information needed for precise engineering or design purposes, as they do not show all sides and angles of an object simultaneously.


What is the measure of the third angle of a triangle if one angle measures 52 degrees?

The third angle is (128 degrees) minus (the second angle).


What is the third angle if the first one is 25 degrees and the second one is 50 degrees?

The third angle of what shape?


The measure of the second angle of a triangle is 21 degrees more then the measure of the first angle the measure of the third angle is 15 degrees less than the measure of the first angle. each is?

Let the measure of the first angle be x⁰. So that the second angle would be (x + 21)⁰, and the third one would be (x - 15)⁰.Since the sum of angle measures in a triangle is 180⁰ we have:x + x + 21 + x - 15 = 1803x = 174x = 58Thus, the first angle is 58⁰, the second angle is 79⁰, and the third angle is 43⁰.


Which countries are using second angle of projection?

The second angle of a triangular parking lot is four times as large as the first angle The third angle is 45 degrees less than the sum of the other two angles How large are the angles?

First angle=X Second angle=4x Third angle=5X-45 Since the angles of a triangle always = 180o x+(4X)+(5X-45)=180o 10X-45=180 10X=225 X=22.5 Therefore. . . First Angle=X=22.5o Second Angle=4X=90o Third Angle=5X-45=67.5o


The measure of the first angle of a triangle is 48 degree.the measure of the second angle is 32 degree .what is the measure in degrees of the third angle?

What if The second angle of a triangle is 20 degrees greater than the first angle. The third is twice the second. Find the three angles.?

Angle 1 = 30 degrees Angle 2 = 50 degrees Angle 3 = 100 degrees.


What is the triangle that has one angle is 40 degrees and a second angle is 50 degrees?

isoselles triangleImproved Answer:-The third angle has to be 90 degrees so it is a right angle triangle.


The second angle in a triangle is four times as large as the first The measure of the third angle is 80 degrees more than sum of the other two angles. Find the measure of the second angle?

Let the first angle be x the second angle be 4x and the third angle be 80+4x+x: x+4x+80+4x+x = 180 Collect like terms: 10x = 180-80 10x = 100 x = 10 Therefore the measure of the second angle is 40 degrees.
