Answer:

  112°

Step-by-step explanation:

The sum of the two smaller angles is equal to the larger one:

  (3x +4)° +(7x +7)° = 161°

  10x +11 = 161 . . . . . . . . . . collect terms, divide by °

  10x = 150 . . . . . . . . . . . . .subtract 11

  x = 15  . . . . . . . . . . . . . . . divide by 10

m∠KHG = (7x +7)° = (7·15 +7)° . . . . . substitute the found value of x

m∠KHG = 112°

The mean of three numbers is 8 two of the numbers are 6 and 11 work out the third number
Andreas93 [3]

Answer:

7

Step-by-step explanation:

To find the number, first multiply 8 by 3, since that is how you find the mean.

8 x 3 = 24 (total)

x + 6 + 11 = 24

x = 24 - 6 - 11

x = 7

Inverse:

7 + 6 + 11 = 24

Mean = 24/3 = 8

Hope this helps!

Answer:

∠y = 62.5°

∠x  =  27.5°

Step-by-step explanation:

z is right angle. ∠z = 90°

∠x = ∠y - 35

∠x + ∠y + ∠z = 180      {Angle sum property of triangle}

y - 35 + y + 90 = 180

y + y - 35 + 90 = 180 {Combine like terms}

  2y  + 55 = 180

          2y = 180 -55      {Subtract 55 from both sides}

          2y = 125         {Divide both sides by 2}

            y = 125 /2

∠y = 62.5°

∠x = 62.5 - 35 = 27.5°

If g(x) = x2 + 2, find g(3). 9 8 11 6
cestrela7 [59]

Answer

Find out the value of g(3)  by using the function g(x) = x² + 2 given in the question .

To proof

The function given in the question is

g(x) = x² + 2

Take  x = 3

put x = 3  in the  g(x) = x² + 2

than it becomes

g(3) = 3² + 2

solving the above

we get

g(3) = 9 + 2

g(3) = 11

Thus g(3) = 11  and option (c) is correct .

Hence proved
