Help!!find the unknown sizes of angles of figure​

Mathematics
1 answer:

Answer:

<h2><u><em>60°</em></u></h2>

Step-by-step explanation:

it looks like  an isosceles triangle, 2 equal side and 2 equal angles (F&E)

the sum of the interior angles in a triangle is 180°, and FH is 180°.

180 - 120 = 60° (angle G)

now we know that it is an equilateral triangle, so Y and 2x are 60°

(3 * 60 = 180°)

-------------------------------

or

180 - 60 = 120

120 : 2 = 60°

Answer:

  1. 30m +50 = 20m +100
  2. m = 5
  3. yes. symmetric property of equality.

Step-by-step explanation:

1. The expression for c in the first equation is (30m+50). Substituting that for c in the equation ...

  c = 20m +100

gives you ...

  30m +50 = 20m +100

__

2. Adding -50-20m to both sides gives ...

  10m = 50

  m = 5 . . . . . . . divide by 10

__

3. Doing the substitution in reverse, you would substitute (20m+100) for c in the equation ...

  c = 30m +50

to get ...

  20m +100 = 30m +50

This is the equation of part 1 with the expressions swapped to the other side of the equal sign. The symmetric property of equality tells you that changing sides of the equal sign does not change the value of the variable(s).

You get the same solution.

What are the solutions of the quadratic equation 4x2 - 8x – 12 = 0?
Juliette [100K]

Answer:

see bottom

Step-by-step explanation:

divide through by 4

x2 - 2x - 3 = 0

x2 - 3x + x - 3 = 0

(x2 - 3x) + (x - 3) = 0

x(x - 3) + 1(x - 3) = 0

(x + 1) (x - 3) = 0

x + 1 = 0 and x - 3 = 0

x = -1 and x = 3
