We want to isolate T. So, we will divided IR from both sides, so our equation is now
P/IR=T
There ya go!
Answer:
104.5
Step-by-step explanation:
do 19x11 then the product you get from that you need to divide by two since it's a triangle.
There are 20 students in the class.
16 - (-15) = 16 + 15 = 31...difference of 31 degrees

so... notice the picture below, the angle in the fourth quadrant
now... notice, the cosine is just the distance the angle makes with the x-axis
so... using the pythagorean theorem, get the opposite side, from that triangle, keeping in mind that, "y" is negative in the 4th quadrant
once you get "y", get any other trigonometry value you need :)
