Answer:
17. z=39/sin45=
y=39/tan60=
x=y/sin60=
19. x=
=6
y=2x=12
z=
Step-by-step explanation:
17.
because:sin45=39/z
so: z=39/sin45=
then: tan60=39/y
so: y=39/tan60=
last: sin60=y/x
so: x=y/sin60=
19.
because: tan60=
/x
so: x==6
then: sin30=x/y
so: y=x*sin30=2x=12
last: sin45=y/z
so: z=sin45*y=
Your answer is going to be 8ab
So,
To find the median, arrange all the numbers from least to greatest.
10, 31, 36, 36, 38, 42, 47, 48, 49, 52
The middle two numbers are 38 and 42. Take their average.
40
40 is the median of 10, 31, 36, 36, 38, 42, 47, 48, 49, and 52.
Answer:
a trapezoid
Step-by-step explanation:
A trapezoid is a convex quadrilateral. A trapezoid has at least on pair of parallel sides. the parallel sides are called bases while the non parallel sides are called legs
Characteristics of a trapezoid
It has 4 vertices and edges
If both pairs of its opposite sides of a trapezoid are parallel, it becomes a parallelogram
Area of a trapezoid = x (sum of the lengths of the parallel sides) x height
Perimeter = sum of lengths of sides of a trapezoid
