Answer:
william is 15 now
Step-by-step explanation:
x+15 = 3(x-5)
x+15 = 3x - 15
15 = 2x-15
30 = 2x
15 = x
15-5 = 10 10*3 =30 15+15 =30
The perimeter of the triangle is about 136
Firstly , let us learn about trigonometry in mathematics.
Suppose the ΔABC is a right triangle and ∠A is 90°.
There are several trigonometric identities that need to be recalled, i.e.
Let us now tackle the problem!
This problem is about Sine Rule.
First of all, we will calculate the ∠C :
∠A + ∠B + ∠C = 180°
72° + 16° + ∠C = 180°
∠C = 180° - 72° - 16°
∠C = 92°
Next, we will use the Sine Rule to find the length of the other side of the triangle.
Finally, we can find the perimeter of a triangle with the following formula
