Answer: -5
Step-by-step explanation:
The formula for calculating the slope of a line is given as :
m=\frac{y_{2} }{x_{2}} - \frac{y_{1}}{x_{1}}
= 8
= 6
= 5
= 15
substituting into the formula , we have
m =
m =
m = -5
Therefore the slope is -5
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
