Question

Find x in the following Figure 125 / 125/x .​

Answer 1

Answer:

x = 110°

Step-by-step Explanation:

Here, two external angles are both 125°

Here, internal angle + external angle = 180°

[As they lie on same straight line.]

Both internal angles = 180° - 125° = 55°

Therefore sum of two internal angles = 55° × 2

= 110°

We know, sum of 3 angles of a triangle is 180°.

Thus, 3rd angle will be : 180° - 110° = 70°

Therefore, x will be = 180° - 70° = 110
