Proving Vertical Angles Are Congruent
1 answer:
The angle ∠22 and angle ∠24 are congruent because they are vertically opposite angles.
<h3>What is an angle?</h3>The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Vertically opposite angle – When two lines intersect, then their opposite angles are equal.
Linear angle – If the total of two angles is 180 degrees, they are said to be linear angles.
The statements are given below.
∠22 = ∠24 (vertically opposite angle)
∠22 + ∠23 = 180 (linear angle)
The diagram is given below.

Answer:
Area of the shape = 240 unit²
Step-by-step explanation:
Shape in the figure attached there are two parts. One is a triangle and other a rectangle.
By adding the area of these two shapes we can get the area of complete shape.
1). Area of the triangle =
Base of the triangle = 20 units
height of the triangle = 4 units
Therefore area of triangle = square units
2). Area of rectangle = Length × width
= 20 × 10 = 200 unit²
Total area of the shape = area of triangle + area of rectangle
= 40 + 200 = 240 unit²
So the answer is area of the shape = 240 unit²
