Answer:
The value of y is 14.
Step-by-step explanation:
To find this, we first can replace the angle written as 2x with 50. Since the sides leading to that point are congruent, we know that they have the same angle.
Now given that fact, we can put the 2 - 50s along with the final angle and set equal to 180 (the measure of the combined angles in all triangles).
50 + 50 + 5y + 10 = 180
110 + 5y = 80
5y = 70
y = 14
Answer:
399/1234
Step-by-step explanation:
