Question

Find the value of x in the triangle shown below. 67

Answer 1

To find the remaining angle, we can utilize the theorem that the sum of angles in a triangle is 180 degrees.

Hence,

`\begin{gathered} x+85^0+67^0=180^0 \\ x+152^0=180^0 \\ \text{collect like terms} \\ x=28^0 \end{gathered}`

Hence, the unknown angle (x) = 28 degrees
