What is the area of a triangle with b=146.2, c=209.3, and a=62.2°? a. 14,563.2 units² b. 12,989.2 units² c. 13,456.7 units² d. 13,533.9 units²

D.) 13, 533.9

Step-by-step explanation:

You can use all the information in the equation of Area when you have side, angle, side. A = 1/2 bc sin A. Use a calculator and it will give you the solution.

maybe - definition of supplementary angles. im not sure. sorry

step-by-step explanation:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
