instrument fitters math
using longhand math find TAN U in a right triangle. use adjacent line segment is 12 in long and its opposite line segment is 12 in Long

what determines how many degrees tubing must be bent
where are the tubing must go
before converting any sine cosine or tangent value into a right triangle to an angle instrument fitters must first determine blank
which angle they are calculating
to find angle R in the tubing installation shown in the figure above first find the blank
SIN R
which of the following represents the reciprocal of SIN
SIN-1
what's the rules for using sine cosine and tangent
SOH/CAH/TOA (some old hoe, caught another hoe, tripping on acid)
a six sided figure that has six equal sides and six equal inside angles is called
a hexagon
which polygon has only 180 degrees in it
a triangle
what is the formula for Pythagorean theorem
a^2 + b^2 = c^2 c^2 - b^2 = a^2 c^2 - a^2 = b^2
one of the most frequent applications of math to the installation of tubing or conduit is when what type of bend is required
an offset
correctly install tubing is installed in a neat fashion with bends that follow existing blank
contours
the ratio of the line segments that is adjacent to the angle of the hypotenuse is called the blank
cosine
the triangle that has all line segments the same length
equilateral triangle
the triangle that has two line segments the same length
isosceles triangle
what should you avoid when bending tubing
kinks or unwanted breaks
what general group of geometric figures does a triangle belong to
polygons
it is an accepted practice to identify the different line segments of a right triangle with
small alphabetic letters
the letter b is usually assigned to what part of the triangle
the base (a=altitude)
what is the name of the line segment directly across from the right angle in a right triangle
the hypotenuse
a fitter has marked a straight piece of tubing to show where the first two bins should be made what should the fitter do next
use an angle finder to find the degrees for the first bend
calculate the length of travel between the two bins for the tubing installation shown in the figure above
19.2
what is the square root of 16
4
tubing offsets are usually fabricated by using blank
45, 30, 22.5 degree angles
using Pythagorean theorem if a equals 3 and b equals 4 C equals blank
5
the ratio between the altitude and the hypotenuse of a right triangle is .8, the length of the hypotenuse is 7.5 cm. what is the length of the altitude?
6
using the proper calculator find the approximate number of degrees and angle b if TAN B equals 1.732
