Answer:
Explanation:
we have a two right triangle, with one side 115
lets say that the other side of the big right triangle is y
-in the big triangle find the third angle
180 -90 -35 = 55, because the sum of all interior angles in a triangle is 180
tan 55 = opp. /adj= y / 115
y = 115 * tan 55
-in the small right triangle
tan 56 = opp./ adj. = 115 / y-x
y-x = 115/ tan 56 , subtract y from both sides
- x= -y +( 115/tan 56), multiply by -1 both sides
x= y -(115/tan56), substitute y for 115 * tan 55
x= (115*tan 55)- (115/tan56)
x≅86.6685
