14. cathy wants to determine the height of the flagpole
shown in the diagram below. she uses a survey
instrument to measure the angle of elevation to the
top of the flagpole, and determines it to be 34.9º.
she walks 8 meters closer and determines the new
measure of the angle of elevation to be 52.8º.
at each measurement, the survey instrument is
1.7 meters above the ground.

52.8
34.9
a
1.7 m
8 m
determine and state, to the nearest tenth of a
meter, the height of the flagpole.

angle addition postulate

2x=56

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.

13664

step-by-step explanation:

=cross multiply

=100 x = 13664
