Explain how you have solved for x and show your workings out. I will award the brainliest 25 points!
Brums [2.3K]

Answer:

The value of x is 10º.

Step-by-step explanation:

From Euclidean Geometry we remember that the sum of internal angles within a triangle equals to 180º. We present the resulting triangle after applying some geometric handling in the image attached below. Then, the triangle satisfies the following equation:

100^{\circ} + (80^{\circ}-5\cdot x)+(4\cdot x +10^{\circ}) = 180^{\circ} (1)

190^{\circ} - x = 180^{\circ}

x = 10^{\circ}

The value of x is 10º.
