Answer:
The angle of elevation of the sun is 39⁰
Stepbystep explanation:
Given;
height of the tree, h = 96 ft
length of the shadow, L = 120 ft

 96ft


θ
120ft
Completing this triangle to cut across the top of the tree gives you a right angled triangle with θ as the angle of elevation of the sun.
Apply trigratio to determine the angle of elevation of the sun;
tanθ = opposite side / adjacent side
tanθ = 96 / 120
tanθ = 0.8
θ = tan⁻¹(0.8)
θ = 38.7⁰
θ = 39⁰
Therefore, the angle of elevation of the sun is 39⁰
Answer:
A
Stepbystep explanation:
Answer:
closed questions are questions with fixed answer options
A. Closed questions allow the respondent to go indepth with their answers.
B. It is possible to automate the collection of results for closed questions.
C. Closed questions allow for new solutions to be introduced.
D. It is easy to quantify and compare the results of surveys with closed questions.
The slope of a line can be found, given two points, as follows:
So this slope tells us the direction of a line and represents the vertical change divided by the horizontal change.
It is 1, at least thats what i got i hope this helped
of the calzone that was leftover. How many of the pieces of the original calzone remain? Explain your reasoning.
Answer:
10 pieces
Stepbystep explanation:
Total no. of pieces of calzone = 24
No of pieces of calzone eaten by sophie = 1/4 of Total no. of pieces of calzone = 1/4 of 24 = (1/4)*24= 6 pieces.
No of pieces of calzone eaten by Glenn = 1/4 of Total no. of pieces of calzone = 1/4 of 24 = (1/4)*24= 6 pieces.
Total no of pieces eaten by both of them on saturday = 12.
No of pieces of calzone left = 2412 = 12
_______________________________________________
No of pieces of calzone eaten by Glenn on next day = 1/6 of Total no. of pieces of calzone left= 1/6 of 12 = (1/6)*12= 2 pieces
No of pieces of calzone left now after Glenn ate 2 of them = 122 = 10.
Thus 10 pieces of original calzone are left .
