What is the value of x of this triangle and angles

x = 9

Step-by-step explanation:

The big triangle is twice as big as the little triangle bc of the info given on midpoints.

So AC is twice as big as DE.

3x - 15 = 2(6)

3x - 15 = 12 ADD 15

3x = 27 DIVIDE BY 3

x = 9

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
