Answer:
Daniel's Mistake was that she didnt add all the sides
Step-by-step explanation:
She only added the right side of the triangle, and the right and bottom sides of the square. She is missing the left of the triangle, which is another 6x-4, and the left side of the square, which is 12x +3.
Using these sides the answer should look like this,
set up your problem
1) (6x-4)*2 + (12x+3)*2 + (14x+13)
multiply your 2's in
2) (12x-8) + (24x+6) + (14x+13)
simplify
3) 50x + 11 is your answer
400 i think i am pretty sure but if it's wronge i apolize
answer is 1.566 deg
Step-by-step explanation:
The angle of elevation is given by the formula
tanθ = height/distance
tanθ = H/ 240
tanθ × 240 = H
θ =( tan∧-1) 240
= <u>1.566 deg</u>
Answer:
she put the numbers in parentheses
Step-by-step explanation:
7x+2y=2
steps:
y+21=-7/2x(x-6)
y+21=-7/2x+21
y=-7/2x+21-21
y=-7/2x
7/2x+y=0
2(7/2x+y=0)
7x+2y=2
