HELP!! 9. What is the area of triangle AOB?
1 answer:
Angles ∠ACD and ∠CAB are congruent because they are alternate angles. Then the area of the triangle AOB will be 22.53 square cm.
<h3>What is the area of the right-angle triangle?</h3>The area of the right-angle triangle is given as
A = 1/2 x B x H
Where B is the base and H is the height of the right triangle.
We know that angles ∠ACD and ∠CAB are congruent because they are alternate angles.
α₁ = 40°
AO = OC = 7.8 cm
Then the area of the triangle will be
Area = 1/2 x 7.8 x 7.8 x tan40°
Area = 22.53 square cm

The Width of the Rectangle =
Step-by-step explanation:
The area of the rectangle
We are told that the width of the rectangle is equal to the greatest common monomial factor of
Let us determine the greatest common monomial factor of
Express each term as a product to pick out the common factors:
In the two terms, the common terms are 10 and . Therefore their greatest monomial factor =
The Width of the Rectangle =
Recall: Area of a Rectangle =Length X Width
