(sorry the picture didn’t download clearly)

These are triangles 1,2 &3. All are missing the angle and each triangle uses one of the three different trig ratios.

Triangle A: Uses the sin ratio, as only the opposite and hypotenuse are labeled with a measurement.

Triangle B:  Uses the tangent ratio, as only the opposite and adjacent sides are measured.

Triangle C: Uses the cosine ratio, as only the hypotenuse and adjacent are labeled.

All the triangles sides are labeled in according to the placement of the missing angle.

I found it really difficult to understand how to do the caliper measurement in imperial units.  I researched and asked for help.

An inch in imperial units is divided in 16 parts and within those parts its divided in 32 and then 64, just multiplying by 2 starting with 4.

So when we are reading the course reading which is the main “ruler” the one that doesn’t move in the middle we have to read it as a fraction of a inch. its two measurements ( the course and then the vernier) that we have to find out and then add together to get our total measurement.

understanding that we cant mix the metric which is centimeter and millimeters and the imperial which is fractions.

Week 3-Math 10

my aha moment was when in an equation with exponents i in ally understood that when there is an exponent outside of the bracket it only is going to affect the first number to its left and that the far left number of the first one in the equation is only to be times the exponent and the first one is to be times the number of times the exponent number is.
