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
