Melissa is standing 40 ft from a tree. the angle of elevation from where she is standing on the ground to the top of the tree is 50°. how tall is the tree? round the final answer to the nearest tenth. enter your answer in the box.

47.7 feet.

Step-by-step explanation:

Please find the attachment.

Let h represent the height of the tree.

We have been given that Melissa is standing 40 ft from a tree. The angle of elevation from where she is standing on the ground to the top of the tree is 50°.

We know that tangent relates opposite side of right triangle with its adjacent side.

Round to nearest tenth:

Therefore, the tree is 47.7 feet tall.

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
