Answer:
B. (x + 16) + (6x − 4) = 180
Step-by-step explanation:
The Cyclic Quadrilateral Theorem states that for a quadrilateral in a circle, the opposite angles will equal 180 degrees. So therefore you can conclude:
∠A + ∠C = 180° which would be (x + 16) + (6x - 4) = 180°
∠B + ∠D =180° which would be x + (2x - 16) = 180°
Answer:
-13
Step-by-step explanation:
-5x + 2 = 67
-5x = 65
5x = -65
x = -13
Answer:
9) <4=89
10) x=35
Step-by-step explanation:
9) 52+39=91
180-91=89
10) 2x+x+13+62=180
3x+75=180
-75 -75
3x=105
105/3=35
