In triangle, ABD,
AD²= AB²+BD²
AB² = AD²-BD²
AB² = 18²-9² = 324-81 = 243
AB = √243
In triangle, ABC,
AC² = AB²+BC²
AC² = (√243)²+(13)²
AC² = 243+169
AC = √412
AC = 20.29
Answer:
5=35
Step-by-step explanation:
we are given the following triangles:
We are asked to determine the value of "y". To do that we will use the tangent of 25:

We solve for "y" by multiplying both sides by "x":

Now, we take the tangent of 15:

Now, we solve for "y" by multiplying both sides by the denominator:

Now, we set both values of "y" equal, we get:

now, we solve for "x". First, we apply the distributive property on the right side:

Now, we substract
