Answer:
200
Step-by-step explanation:
the formula for working out the area is to multiply the length by the width.
so for this you would multiply 100 by 2 which gives you 200 cm squared
Sum of all the interior angles = (5-2)x180 = 540°
540 - 100 - 120 - 100 - 90 = 130°
So the last unknown angle in the polygon is 130°
Sum of all the adjacent angles on a straight line is 180°
Angle 1 = 180 - 130 = 50°
Answer:
22,203 ft^2
Step-by-step explanation:
The area of a triangle with angle ∅ and two sides a and b is;
Area A = 1/2 × absin∅ ......1
The park is in the shape of a triangle, with two sides and an angle given;
Given;
a = 190 ft
b = 235 ft
∅ = 84°
Substituting the values into equation 1;
Area of the park;
A = 1/2 × 190 × 235 × sin84°
A = 22,202.70131409 ft^2
A = 22,203 ft^2 (to the nearest whole number)
Area of the park is 22,203 ft^2
your options are Put the point of the compass on point B and the pencil point on point C. With the compass point still on B, draw two arcs that intersects the circle with center A.
Use a straightedge to join the four points where the circles intersect.
Draw and label the points where the circles with centers A and B intersect and where the circles with centers A and C intersect.
Put the point of the compass on point B and the pencil point on point C. Using this compass width, put the compass point on A and draw another circle.
