A strong wind breaks the trunk of a 42-meter-tall tree. The upper part of the tree tips over until its top hits the ground. This upper part makes an angle of 55º with the ground. To the nearest tenth, how far up the trunk did the tree break?

step-by-step explanation:

.6 is 1/2 of 12

the answer is actually d. i just took the test

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

d 600 because 15*10*2=300

300+300=600

step-by-step explanation:

final total: 63
