HELP ASAP!!!!<br> GIVING BRAINLIEST!<br><br> Find the value of x and y with the steps PLEASE.
PtichkaEL [24]

Answer:

x=70

y= 40

Step-by-step explanation:

the triangle containing x is an isosceles triangle so two of the sides are 55.

55+55+x=180.

110+x=180

110-110+x=180-110

x=70

Triangle BAC is equilateral so 180/3=60. Now

x+60+c=180

70+60+c=180

130+c=180

130-130+c=180-130

c=50

That gives us one corner of triangle CBD. We know a second angle is 90 so

50+90+y=180

140+y=180

140-140+y=180-140

y=40

I think that is correct but you are free to check it yourself

The altitude a ( in feet) of a plane t minutes after lift off is given by a=3400t+600
Julli [10]

Answer:

  6 minutes

Step-by-step explanation:

'a' in the formula represents altitude in feet. You are told the altitude is 21000 feet, so put that into the formula:

   21000 = 3400t +600

You can solve this for t:

  20400 = 3400t . . . . . subtract 600 from both sides

  6 = t . . . . . . . . . . . . . . . divide both sides by 3400

The problem statement tells you that t represents minutes after lift off, so this solution means the altitude is 21000 feet 6 minutes after lift off.

The question is asking for the number of minutes after lift off that the plane reaches an altitude of 21000 feet, so this answers the question directly:

  The plane is at an altitude of 21000 feet 6 minutes after lift off.
