3x4=5x-10
12=5x-10
22=5x
x=4.4
x=15-657/2=15-373/2=-5.316
x=15+657/2=15+373=20.316
Answer:
42
Step-by-step explanation:
If we suppose the value is constant,
Divide 30/5 we get 6.
so now we know for every 1 x we get 6 y.
Multiply 6 times 7 = 42.
The value of y = 42 when x = 7.
The angle subtended by two chords is half the enclosed arc measure. If we imagine one of the chords getting shorter and shorter this remains true. In the limit the shrinking chord becomes a tangent, and the angle is still half the arc measure.
Answer: 70 degrees
