Question

plezzz help....its would be very appreciated

Answer 1

the first question and the answer i have is wrong

Answer 2

and all three parts of it

Answer 3

question 15
a)
first find the angle
let angle is a
tan(a)=180/235

a=37.45
let b is the angle which is for upper triangle.
b=90-a =90-37.45=52.55
tan(b)=x/235
x=tan(b) *235= tan(52.55) *235=306.8
height h = x+180 =306.8+180=486.8=487 fts
b)
that is x=307 fts
c)
using pythagorian theorem
d=sqrt(307^2+235^2)
d=386.6=387 fts

Answer 4

i did not use tan, since this 2nd angle split another - i knew this was a 45-45-90 triangle and used special properties

Answer 5

gud luck @smilz39

Answer 6

This can be solved using similar triangles.

Answer 7

I assume part (a) means what is x? x= 307
part (b) is x+180 = 487

part(c) you can use the pythagorean theorem. with sides 307 and 235 (see rose's answer)
