What is first angle projection and it symbol?
First angle projection is the one in which the object is placed in the first quadrant and views are projected on the planes. Refer this link for illustration and symbol http://www.technologystudent.com/designpro/ortho1.htm
Two angles are complimentary The sum of the measures of the first angle and half the second angle is 69.5 degrees Find the measures of the angles?
A system of equations needs to be created. Complimentary means that the two angles equal to 90 degrees. The first equation will be x + y = 90 The second equation will be x + .5y = 69.5 Using the elimination method multiply the first equation by -1 This will leave us with -x - y = -90 Add the second x + .5y = 69.5 X is eliminated When adding -y = -90 and .5y = 69.5 we are left with: -.5y = -20.5 Divide by -.5 y = 41 This is the second angle Substitute 41 for y in the first equation x + 41 = 90 x = 49 This is the first angle To check substitute both numbers into the second equation 49 + .5(41) = 69.5 49 + 20.5 = 69.5 69.5 = 69.5 Or Given the sum of the first angle and the half of the second angle is 69.5, means that the second angle is 2(90 - 69.5) = 41. Therefore, the first angle is (90 - 41) = 49.
What will the measure of the second acute angle be if the first is 28?
If its a right angle triangle then the second acute angle is 62 degrees
How do you interpret first and third angle drawings?
First angle is interpretted by the drawing being positioned to the right of the section and third angle is interpretted by the elevation being positioned to the left of the section.
