We need to find a tree such that the angle of elevation from the end of the shadow to top of the tree is 40 degrees.
The length of the shadow is the adjacent side and is 35.
The height of the tree is the opposite side. Let it be x.
Tan ratio = opposite/adjacent
tan(40) = x/35
x = 35*tan(40) = 29.37
Answer: Height of the tree is 29 feet

Answer:
2 students failed the test.
Step-by-step explanation:
There are 40 students and 95% passed. 95% is also equal to 0.95. Since we are looking for the students who failed, subtract 1.00 - 0.95. You get 0.05. The percentage of students who failed is 5%. Multiply 0.05 times 40 to get 2. This is the amount of students who failed.
Answer:
y= -4x-7 or 4x+y= -7
Step-by-step explanation:
we know y=mx+c
given,
m=-4 c=-7
the equation y= -4x-7 or 4x+y= -7
thank u
