Answer:

132-5 therefore the height from the eyes to the window is 127

100 feet away from the base of the tower  

This forms two legs of a triangle

trying to find the degrees of this triangle.

Since its the two legs, you can use tanx which = to opposite side/adjacent side

Therefore, it is tanx = 127/100

But you are looking for x so arctan(1.27)

Must use calculator to find x.

Lesson 2-3
malfutka [58]

Answer:

18. g= -3

19. x= -1

20. n= 3

21. p= -1

22. d= -3

23. a= 5

Step-by-step explanation:

how to solve the variable (using 18 as an example)

step 1: simplify both sides of the equation.

20+g+g=14

(g+g)+(20)=14(combine like terms)

2g+20=14

2g+20=14

step 2: subtract 20 from both sides.

2g+20−20=14−20

2g=−6

step 3: divide both sides by 2.

2g/2 = -6/2

Triangle DEF is an isosceles, so DEF = DFE.
Katarina [22]

Answer:

m∠CFD=105\°

Step-by-step explanation:

we know that

m∠CFD+m∠DFE=180\° ------> by supplementary angles

we have

that

m∠DFE=m∠DEF=75\°

so

m∠CFD+75\°=180\°

m∠CFD=180\°-75\°=105\°
