Question

Find the value of x. (ITS URGENT FAST PLESS)

Answer 1

Step-by-step explanation:

as they are cyclic quad the sum of opp angles is 180 therefore (x+20)+(2x-20)=180 which means 3x=180. x=60

Answer 2

Answer:

we know that the opposite angles of the parallelogram are 180⁰ and the angles on the same line segment together make 180⁰

a)

• (2x-20)⁰ + (x+20)⁰ = 180⁰
• 2x - 20 + x + 20 = 180
• 3x = 180
• x = 180/3
• x = 60

b)

• 110⁰ + 5x =180
• 5x = 180-110
• 5x = 70
• x = 70/5
• x = 14

c)

• 2x + 100 = 180
• 2x = 180 - 100
• 2x = 80
• x = 40

if you understand plese thanks me

and make me brainiest
