The crane is 139.8cm tall.
<h3>what is angle of elevation?</h3>
The angle formed by the line of sight and the horizontal plane for an object above the horizontal.
Using Trigonometry
tan 30 = h/y
1/√3 = h/y
y= h√3
and, tan 25= h/y+62
0.96= h/(h√3 +62)
h= 0..96 (h√3 +62)
h= 0.96*h*1.732+0.96*62
h=0.796h +28.52
0.2404h= 28.52
h= 139.8 cm
Hence, whooping crane is 139.8 cm.

Hope this helped :)
The answer will be “self interest”.
You could do this step by step or all in 1 statement. I will do it step by step because that's the way I would teach it.
i1
i1 = 4 * (1/2)^(1 - 1) Reduce the power
i1 = 4 * (1/2)^0 Change 1/2 to 1
i1 = 4 * 1 = Multiply 4
i2
i2 = 4 * (1/2)^(2- 1) Same directions as above
i2 = 4*(1/2)^1
i2 = 4*1/2 = 2
i3
i3 = 4 * (1/2)^(3 -1) Same directions as above.
i3 = 4 * (1/2)^2
i3 = 4 * 1/4
i3 = <u>1</u>
Total 7
