Answer:

72°

Step-by-step explanation:

Triangles have angles that equal 180°

Knowing this we can use 180 - 38

180-38 = 142

Since both angles have the same values of 21 we know that their angles will be the same

So, 142 ÷ 2 equals 72

Answer: 71°

Step-by-step explanation:

Since the triangle is having two equal sides, it is an isosceles triangle, therefore it will also have equal angles.

Since one of the angle is X, the two angles will be 2X

2X + 38° = 180° ( sum of interior angles in a triangle)

2X = 180° - 38°

2X =142°

To get just one of the angles which the x is representing in the figure, we simple divide bothside by 2

2X/2 = 142/2

X = 71°

Question 12 onlyyyyyyyy
netineya [11]
For number 12 you need to make an expression using the information given. a) 25g + 18r + 15b could be the expression.
b) The variables would be 25g for the 25 gold seats, 18r for the 18 red seats and 15b for the 15 blue seats. 
c) Plug in the number given according to the variables.
       25(100) + 18(250) + 15(200)
             2500 + 4500 + 3000
                   7000 + 3000
                        $10,000

Rewrite the function by completing the square. h(x)= x^{2} +3 x -18 left parenthesis, x, right parenthesis, equals, x, squared,
ludmilkaskok [199]

Answer:

  h(x) = (x +1.5)^2 -20.25

Step-by-step explanation:

We assume you want to rearrange h(x)= x^2 +3x -18.

Recognize the coefficient of x is 3. Add and subtract the square of half that. (3/2)^2 = 9/4 = 2.25

  h(x) = (x^2 +3x +2.25) -18 -2.25

Now, write the expression in parentheses as a square, simplify the constant.

  h(x) = (x +1.5)^2 -20.25 . . . . . . . . vertex form
