Answer:
1
Step-by-step explanation:
When a quadrilateral is inscribed in a circle, the opposite angles are supplementary
The description of the angles in the quadrilaterals are:
- b. m∠M = 55°, m∠J = 48°, and m∠L = 132°
- d. m∠L = 40°, m∠M = 60°, and m∠K = 120°
- e. m∠K = 72°, m∠L = 44°, and m∠M = 108°
- f. m∠J = 105°, m∠K = 65°, and m∠L = 75°
<h3>How to describe the angles</h3>
The quadrilateral is given as: JKLM
The opposite angles are:
- Angles J and L
- Angles K and M
The opposite angles are supplementary
So, we have:


Next, we test the options
<u>Option (a)</u>


This is not true
<u>Option (b)</u>


This is true
<u>Option (c)</u>


This is not true
<u>Option (d)</u>


This is true
<u>Option (e)</u>


This is true
<u>Option (f)</u>


This true
Hence, the description of the angles in the quadrilaterals are (b), (d), (e) and (f)

Answer: 9pi
Step-by-step explanation:
Answer:
55
Step-by-step explanation:
The three angles form a straight line, so they add to 180.
x + x + 70 = 180
Combine like terms
2x+70 =180
Subtract 70 from each side
2x+70-70 =180-70
2x= 110
Divide by 2
x = 55
SQT = x
So SQT = 55
