ANSWER
The solution is where the two graphs intersect, which is
EXPLANATION
The given system of equations are
and
We need to graph the two equations.
Let us graph
first.
We need at least two points.
You can choose any appropriate value for x and solve for y. Choosing zero makes our working easier. So let us plot the intercepts.
When
So this gives us the ordered pair,
When
we get,
This also gives the ordered pair
We plot these two points and draw a straight line through them to obtain the blue graph in the attachment.
For the second line
We again find the intercepts and plot them.
When
This gives the ordered pair
Also, when
then we have,
Then we again have the ordered pair,
We plot these two points on the same graph sheet to obtain the red graph above.
The intersection of the two lines is
You will get good grades so don't worry much.
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
