Hi there!
Something really good to remember about trigonometry is SOHCAHTOA. I won’t dive into too much detail about it, but you should google it for future assignments.
Anyways,
tan50°=14/AB
ABtan50°=14
AB=14/tan50°
AB=11.75
cos50°=14/AC
ACcos50°=14
AC=14/cos50°
AC=21.78
For the measure of angle C you can use a theorem called the third angle theorem. In every single possible triangle, the sum of all three angles adds up to 180°. You can set up an equation like so...
angleC=180-(90+50)
angleC=180-140
angleC=40°
12+ 9.6+ 7.2=28.8 miles is the perimeter
28.8
Answer:
Its A because it is
Step-by-step explanation:
5 x 0.5 x 3.14 = 7.85
Answer:

Step-by-step explanation:
Using Pythagoras' identity in the right triangle
The square on the hypotenuse h is equal to the sum of the squares on the other 2 sides, that is
h² = 2² + 3² = 4 + 9 = 13 ( take square root of both sides )
h = 
-24 7
sorry don,t know how to get the symbol
