Since they are just next to each other ill take it multiplication and that would be 128 if its not let me know and ill correct it
Answer:
The angle of elevation of the sun is 38°
Step-by-step explanation:
We can set up the diagram for the the question by interpreting it, you can check the diagram at the attached file.
We can see that after the interpretation of the question we arrived at a triangle,. Where the vertical side represent the 92-ft. which is the height of the tree and the horizontal side represent the 120 ft. which is the shadow's lenght. Then the angle of elevation of the sun can ba calculated using tangent ratio, from our knowledge of trigonometry
Tan(θ )= opposite/adjacent
Where our opposite =92ft
Adjacent= 120ft
Tan(θ ) =92/120
θ =tan-1( 92/120)
θ = 37.48°
Therefore, the angle of elevation of the sun If we round up our decimal value to the nearest 10th, we have θ = 38°
Answer:
2
Step-by-step explanation:
Coefficients are always the number being multiplied by (or attached to) the variable, which is shown by a letter
so in 2x, 2 is the coefficient, and x is the variable
7x^2 -10x +3 = 0
Use the quadratic formula
a = 7 b = -10 c=3
x= [--10 +-sq rt(100 - 4*7*3)] / 2*7
x= [--10 +-sq rt(100 - 84)] / 14
x= [10 +-4] / 14
x1 = 14/14 = 1
x2 = ([6] / 14) = 3/7
