Find the value of x PLEASE EXPLAIN
2 answers:
We can say that:
- In the first triangle, x = 57°
- In the second triangle, x = 111°
We must know that the sum of all the internal angles of a triangle is equal to 180°. So, just solve an equation to determine x in each triangle.
<h3>First triangle:</h3>- 67 + 56 + x = 180 → Sum:
- 123 + x = 180 → We move 123 to the other side, changing its signal.
- x = 180 - 123 → Subtract:
- <u>x = 57°</u>
- 22 + 47 + x = 180 → Sum:
- 69 + x = 180 → We move 69 to the other side, changing its signal.
- x = 180 - 69 → Subtract:
- <u>x = 111°</u>

If you notice the picture below
the composite figure is just a trapezoid sitting on top of a rectangle
and then, the rectangle has a triangular hole in it
so.. get the area of the trapezoid
then get the area of the rectangle, which is just a 12x14
and then get the area of the triangle, which surely you know is 1/2 bh
then, subtract the triangle's area from the rectangle's area
and whatever is left, namely the difference, add that to the area of the trapezoid, and that's the composite's area
namely the area of the trapezoid plus the rectangle's, minus the triangle's
