Answer:

  • Angle ESH = 107°
  • Angle HRE = 73°

Explanation:

A cyclic quadrilateral is a quadrilateral that can be inscribed in a circle, meaning that all four vertices of the quadrilateral lie on the same circle. Cyclic quadrilaterals have a number of properties that are not shared by other quadrilaterals.

Some of the properties of cyclic quadrilaterals include:

  • The sum of the opposite angles of a cyclic quadrilateral is always 180 degrees.
  • The diagonals of a cyclic quadrilateral bisect each other at right angles.
  • The product of the diagonals of a cyclic quadrilateral is equal to the sum of the products of the opposite sides.
  • The area of a cyclic quadrilateral can be found using Brahmagupta's formula.

In this case:

We use the property:

The sum of the opposite angles of a cyclic quadrilateral is always 180 degrees.

So,


\sf (2x+7) ^\circ+(x+23)^\circ = 180^\circ

Solving like terms


\sf 2x+7+x+23= 180


\sf \sf 3x +30 =180

Subtracting both sides by 30.


\sf 3x = 180 - 30


\sf 3x = 150

Dividing both sides by 3, we get

\sf x =(150)/(3)


\sf x =50

Now,

m ∡ ESH =
\sf (2x+7)^\circ = (2*50+7)^\circ = 107^\circ

m ∡ HRE =
\sf (x+23)^\circ = (50+23)^\circ =73 ^\circ

Therefore,

  • Angle ESH = 107°
  • Angle HRE = 73°
