A. From point C, Clay walks the distances CA and CB. Then he measures the angle between these line segments. What is the distance to the nearest meter from A to B? Round intermediate results to 3 decimal places. b. From another point F, Clay measures 20 meters to D and 50 meters to E. Reece says that last summer this area dried out so much that he could walk the 49 meters from D to E. What is the measure of F? Around intermediate results to 3 decimal places and the final answer to 1 decimal place.
c. Reece tells Clay that when the area defined by triangle DEF dries out, it becomes covered with native grasses and plants. What is the area of this section? Round intermediate results to 3 decimal places and the final answer to 1 decimal place.

PLEASE ANSWER I HAVE TO KNOW THIS BY THE END OF THE DAY (2/24) **65 points

this answer is !

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

answer

you start with $5 and save $10 a week until you have at least $45wer

step-by-step explanation:

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
