The answer should be 164, if the angles are vertical (across from another) they are the same so 164 times 1/2 is 82
Answer:
Answer is: (9)
Step-by-step explanation:
105+(8v+3)=180
(8v+3)=75
8v=72
v=9
2 is in the tens. 9 is in the hundredths. 0 is in the thousandths.
Answer:
53 degrees
Step-by-step explanation:
Angle N = angle E
because angle made by joining end points of same chord on circumference are always equal.
so angle E = 37
Angle D = 90 ( because angle made by diameter on circumference is 90 degrees)
Now in Triangle DEC. Sum if all the angles of triangle us 180
Angle D + angle E + ? = 180
37 + 90 + ? = 180
127 + ? = 180
? = 180 - 127
? = 53 degrees
