?find the mising angles of the following polygons 1st angle is 60 2nd angle is 70 find another another two angles?

Question

Answer

Missing Angles of a Polygon

Step 1: Determine the total number of angles in the polygon using the formula (n-2) x 180, where n is the number of sides of the polygon.

Step 2: Subtract the sum of the given angles from the total to find the sum of the missing angles.

Step 3: Divide the sum of the missing angles by the number of missing angles to find the measure of each missing angle.

Example:

Given two angles of a polygon are 60 and 70. Find the measure of the other two angles.

Step 1: The polygon has n = 4 sides, so the total number of angles is (4-2) x 180 = 360 degrees.

Step 2: Subtract the sum of the given angles (60 + 70 = 130) from the total (360) to find the sum of the missing angles: 360 - 130 = 230 degrees.

Step 3: Divide the sum of the missing angles (230) by the number of missing angles (2) to find the measure of each missing angle: 230/2 = 115 degrees.

Therefore, the other two angles of the polygon are both 115 degrees.

Answer

Angle A is 60.angleB is 70. angle C is x
angleA+angleB+angleC=180
60 +70 +x=180
130+x=180
x=180-130
x=50
