don't know about that purple one.
Answer:
Perimeter of is .
Explanation:
Given: In , , and AD= 8cm.
In
Sum of the measure of the angles of triangles is 180 degree.
or
Simplify:
∵ AD= 8cm and to calculate the length of CD we use tangent ratio i.e,
then;
or
Simplify:
cm.
Also, find the length of AC, we use sine ratio i.e, .
Then,
or
On simplify:
cm.
Now, in triangle ABC;
, then
[Sum of the measure of the angles in the triangle is 180 degree]
To calculate the length of BC;
[∴ ]
therefore,
or
Simplify:
cm.
Using Pythagoras theorem in triangle ACB;
Let BD be x cm
AB = 8+x cm , AC = 16 cm and cm
or
or
Simplify:
x=24 cm
Therefore, the length of AB = 8+x= 8+24=32 cm
Perimeter(P) of triangle ABC is equal to the sum of the sides of the triangle.
⇒ P= AB+BC+AC = cm
Answer:
Step-by-step explanation:
The answer is A.
