Answer:
Step-by-step explanation:
Given sinα=−2/3, before we can get secα, we need to get the value of α first from sinα=−2/3.
Taking the arcsin of both sides
Since sin is negative in the 3rd and 4th quadrant. In the 3rd quadrant;
α = 180°+41.8°
α = 221.8° which is between the range 270°<α<360°
secα = sec 221.8°
secα = 1/cos 221.8
secα = 1.34
Answer: THIRD OPTION.
Step-by-step explanation:
The missing figure is attached.
You can observe in the figure two equal right triangles: RST and RSV.
Notice that:
Knowing that:
You can substitute values into the equation and solve for "x":
Now, you can identify in the figure that:
Having the value of "x" calculated above, you can subsitute into the equation and evaluate, in order to find the length of segment RV:
Since:
You get that:
Finally, you must add RT and RV in order to find the length of the segment TV. This is:
3^-6
is equivelant to 9^-2
