Explanation

All angles in a triangle add up to 180 degrees.

2. Which one are a Cyclic Quadrilaterals?

Option 1

Option 2

Option 3

Option 4

Cyclic quadrilaterals are quadrilaterals that can be inscribed in a circle, meaning that all four vertices of the quadrilateral lie on the circumference of a circle. Since the question asks for a cyclic quadrilateral, the correct answer would be Option 3.

Explanation

Cyclic quadrilaterals are quadrilaterals that can be inscribed in a circle, meaning that all four vertices of the quadrilateral lie on the circumference of a circle. Since the question asks for a cyclic quadrilateral, the correct answer would be Option 3.

3. What is the value of b and c?

B=95 c=100

B=100 c=90

B=90 c=110

B=110 c=95

The given answer states that the value of b is 110 and the value of c is 95. This means that b is greater than c.

Explanation

The given answer states that the value of b is 110 and the value of c is 95. This means that b is greater than c.

4. What is the sum of the opposite interior angles?

90

180

270

360

The sum of opposite interior angles in a polygon is always 180 degrees. This is a well-known geometric property that applies to all polygons, regardless of the number of sides. Therefore, the correct answer is 180.

Explanation

The sum of opposite interior angles in a polygon is always 180 degrees. This is a well-known geometric property that applies to all polygons, regardless of the number of sides. Therefore, the correct answer is 180.

5. The diagram below shows a cyclic quadrilateral /PQRS and a straight line RST. Calculate the value of /PST.

150

120

50

30

In a cyclic quadrilateral, opposite angles are supplementary, meaning they add up to 180 degrees. In this case, angle PST and angle PQR are opposite angles. Since angle PQR is given as 150 degrees, angle PST must be 180 degrees minus 150 degrees, which equals 30 degrees. However, the question asks for the value of angle /PST, which is the same as angle PST. Therefore, the value of /PST is 30 degrees.

Explanation

In a cyclic quadrilateral, opposite angles are supplementary, meaning they add up to 180 degrees. In this case, angle PST and angle PQR are opposite angles. Since angle PQR is given as 150 degrees, angle PST must be 180 degrees minus 150 degrees, which equals 30 degrees. However, the question asks for the value of angle /PST, which is the same as angle PST. Therefore, the value of /PST is 30 degrees.

6. Find the value of x,y, and z.
