Let's solve this by using the quadratic formula:
Note that we only use the coefficients so a=12, b=-14, and c=-6.
Plug values in the quadratic equation:
And so by evaluating those values we obtain:
Now we have two answers which are our factors one where we add another where we subtract and so:
First factor:
Second Factor:
And so your factors are
meaning that those are your roots/x-intercepts.
Answer:
63.5
Step-by-step explanation:
using soh-cah-toa, you can determine that the x and the value given are sin(theta). Sin is opposite over hyp.
thus,
once you solve that you get the angle x equals to 63.4746 which can be rounded to 63.5°
