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?
100.
The sum of the first two angles of a triangle are twice the measure of the third angle The first angle is half of the second angle What are the three angles?
The angles are 40, 80 and 60 degrees.
If two angles of a triangle each measure what is the measure of the third angle?
180- total of the first two angles= 3rd 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 difference between first and third angle drawings?
It is just where the elevation is positioned, first angle, the drawings is positioned to the right of the section and third, the elevation is positioned to the left of the section, obviously rotated the correct way too.
What are the 2 types of oblique drawing?
first angle projection and third angle projection.
What is the measurement of the third angle of a triangle if the first two were 45 degrees?
If the first two add up to 45 degrees, then the third angle is 135 degrees.If each of the first two is 45 degrees, then the third angle is 90 degrees.
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?
What are the advantages of third angle projection over the first angle projection?
Neglecting term "opposite".. In third angle projection, what we see are what are we going to draw
What are the two main types of projection in autocad?
first angle, third angle
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.
Can you show me the difference between first and third angle projection?
In a first angle projection, the object stands in between the observer and the plane of projection. In a third angle project, the object and the plane of projection is interchanged.
What is the measure of the third angle of the triangle?
The third angle of a triangle is equal to 180 degrees minus (the sum of the first two angles).
Advantages of a third angle drawing?
Third angle projection is in common use in the USA, Canada, and the UK. The rest of the world more commonly uses first angle. There is no inherent superiority of one projection over the other. When you are making drawings that may be used internationally, it's a very good idea to indicate by a small symbolic diagram which projection is in use. This diagram is usually a side and end view of a truncated cone.
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.
How do you interpret first and third angle projection?
The front elevation is in the centre in both projections. In 1st angle projection the end elevation is on the opposite side of the front elevation and the plan view is below the front elevation. In 3rd angle projection the plan view is above the front elevation and the end elevations are on the same side as viewed
