While standing exactly halfway between two tall trees, nikki spots a blue jay at the top of one tree and a cardinal at the top of the other. from nikkis point of view, the angles of elevation to the blue gay and to the cardinal are 60 degrees and 50 degrees, respectively. the trees are 40m apart. if nikki is 1.5 m tall, find the height of each tree

i dont have an answer

step-by-step explanation:

answer:   b

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
