Suppose there is a triangle with sides a, b, and c and angles A, B, and C. Using the known
given information below and the law of cosines, what is the measure of angle A? Round
your answer to the nearest whole number, if necessary.
a = 10 cm
b= 17 cm
c= 11 cm

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
