Answer:
3.2
Step-by-step explanation:
If there are 2 secont lines intersecting inside a circle like the picture shown, then the theorem tells us that <em>"the product of 2 segments of one secant line is equal to the product of 2 segments of other secant line"</em>
<em></em>
Thus, we can say that:
x * 10 = 8 * 4
10x = 32
x = 32/10
x = 3.2
Answer:
B and C
Step-by-step explanation:
They are on the same line so they ad up to 180 and are supplementary
Answer:
55
Step-by-step explanation:
sinx = opposite/hypotenuse = 9/11
x = arcsin(9/11) = 54.9031987, which is about 55, degrees
Answer:
Step-by-step explanation:
Triangles ADC and ACB are similar.
Therefore AC / AB = AD / AC
6 / AB = 4 / 6
4AB = 36
AB = 9 (answer).
Split the first half of the decimal (14) by 2, to get 7, then half the second aspect (.6) to get .3, meaning that 14.6 divided by two is 7.3
