How do I find the measurements of this triangle

1 answer:

Using sine law:

9/sinc = 15/sin22

sinc = 9sin22 / 15 = 0.225

so c = sin^-1(0.225) = 12.99 degrees ~~ 13 degrees

if B was required:

B = 180 - C - A ~~ 145

evablogger [386]

If the rate of change (ROC) of the function is quadratic, then the function type is cubic

<h3>What is rate of change?</h3>

The rate of change of a function is the rate at which the output values change over the input value

This means that, a cubic function will have a quadratic rate of change
