Solution

Step 2: Use the given angles in the triangle to set up the equation \(c + 30^{\circ} + 90^{\circ} = 180^{\circ}\). Step 3: Solve for \(c\) by subtracting the sum of the known angles from \(180^{\circ}\), which gives \(c = 180^{\circ} - 90^{\circ} - 30^{\circ}\). Step 4: Calculate the value of \(c\), which is \(c = 60^{\circ}\). So, the size of angle \(c\) is \(60^{\circ}\).Click to rate:20.4(54 votes)Search questionBy textBy image/screenshotDrop your file here orClick Hereto upload
