Answer:
25.8 ft
Step-by-step explanation:
Draw a right triangle with the right angle at the foot of the tower. The interior angle of the triangle at the top is the complement of the angle of depression. 90 - 74 = 16; it measures 16°. The leg at the bottom has length x. The height of the tower is the vertical leg and is 90 ft. We are looking for x.
For the 16° angle, x is the opposite leg, and 90 ft is the adjacent leg.
tan A = opp/adj
tan 16° = x/(90 ft)
x = 90 ft * tan 16°
x = 25.8 ft
Answer: 25.8 ft
Answer:
x=1 and -3
Step-by-step explanation:
log(x)+log(x+2)=log(3)
log(x(x+2))=log(3)
x(x+2)=3, simple quadratic. x=-3 and 1. Answered by Gauthmath
Hey there!
A binomial is a polynomial that contains two terms. Terms are separated from one another by mathematical symbols, such as +, –, and ×. A term can be a variable, a variable with a coefficient, a constant, or really any combination of coefficient, variable, and exponent that you can think of. For example...
(3x² – xy)
(x + 3)
(5x – 6y)
...are all binomials.
Hope this helped you out! :-)
I'm pretty sure it is d, you are combining the terms which is the same thing.
