Answer:
65
Step-by-step explanation:
Angle M and angle L are supplementary angles, so they add up to 180°.
180 - 115
= 65
The measure of angle L is 65 degrees.
Using the law of Tangents:
Tan(angle) = Opposite leg / Adjacent leg.
Using the provided information:
Tangent (61) = BC / 5.7
Solve for BC:
BC = 5.7 x tangent(61)
BC = 10.3 miles ( rounded to the nearest tenth).
I am not completely sure but 2.7 because I subtracted the 6 8/9 by 6 4/9 and got 8/3 which then I dived and got 2.66666666666667
