Answer: im pretty sure this is correct
- 1/42 x (21x233y)
Step-by-step explanation:
first convert the expressions (2 3/10x x5/7 x y-2 4/5 x x )
then factor the expression (23/10 x- 5/7 y- 29/6 y- 14/5x )
then collect like terms (1/210 x 483 x - 150 y - 1015 - 588x)
factor the expression (1/210 x 105x 1165y)
Multiply reduce (1/210 x -5 (21x + 233y ))
= -1/42 x (21x233y)
Dawg it gotta be prolly maybe bourse not D. 7/2
2x + 9 = -65
2x = -65 - 9
2x = -74
x = -74/2
x = -37
So, your final answer is -37
Hope this helps!
Answer: 61.16 ft
Step-by-step explanation:
We can think in this situation as a triangle rectangle.
where:
The height of the tree is one cathetus
The shadow of the tree is the other cathetus.
We know that the angle of elevation of the sun is 78°, an angle of elevation is measured from the ground, then the adjacent cathetus to this angle is the shadow of the tree. And the opposite cathetus will be the height of the tree.
Now we can remember the relationship:
Tg(A) = (opposite cathetus)/(adjacent cathetus)
Where:
A = 78°
Adjacent cathetus = 13ft
opposite cathetus = height of the tree = H
Then we have the equation:
Tg(78°) = H/13ft
Tg(78°)*13ft = H = 61.16 ft
