What is the area of the triangle? round only your final answer. round to the nearest tenth

Answer

10.5 units

Explanation

1. We have been given the measure of one angle and a length.

2. Apply tan.

tan(60) = 6/x

6/tan(60) = 3.5

The missing side length rounded to the nearest tenth is 3.5

3. Solve for the area

The area of a triangle can be found using the formula base * height/2

6 * 3.5/2 = 10.5

The area of the triangle is 10.5 units

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
