Answer:
30°
Step-by-step explanation:
Consecutive interior angles are supplementary when the lines are parallel:
2x +4x = 180°
x = 180°/6
x = 30°
_____
<em>Comment on units</em>
A lot of times the angles are assumed to be measured in degrees. Using that assumption, x=30 (degrees). When no units are specified, the angle measure defaults to radians. In radians, x = π/6. (We rarely see problems of this nature where the angles are expected to be measured in radians. More often, we see poorly edited questions where angles need to be assumed to be measured in degrees.)
There's a big triangle with base (2+6) meters and altitude 5 meters.
The formula for the area of a triangle of base B and altitude H is
A = BH/2.
The area of the large triangle is thus A = (8 meters)(5 meters)/2, or
20 square meters.
Use A = BH/2 to find the areas of the other triangles.
