(a)
To find: The altitude of the triangle.
(a)
Answer to Problem 8CFU
Explanation of Solution
Given information: Geometry: Each base angle of an isosceles triangle measures
Calculation:
To find the altitude I have taken the right side of the left triangle in the sketch and redrawn it to the right.
We are looking for the opposite side and know the hypotenuse so this is a sine problem.
I also change the
(b)
What is the length of the base?
(b)
Answer to Problem 8CFU
Explanation of Solution
Given information: Geometry: Each base angle of an isosceles triangle measures
Calculation:
To find the base I have taken the right side of the left triangle in the sketch and redrawn it to the right.
We are looking for the adjacent side and know the hypotenuse so this is a cosine problem.
I also change the
Now double this to get the base of the triangle
(c)
To find: The area of the triangle.
(c)
Answer to Problem 8CFU
Explanation of Solution
Given information: Geometry: Each base angle of an isosceles triangle measures
Calculation:
Now we have simply
