Answer:
Step-by-step explanation:
<em><u>This</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>because</u></em><em><u> </u></em><em><u>of</u></em><em><u> </u></em>
Where when two lines intersect the vertically opposite angles are always equal.
<em>Hence</em><em>,</em>
<em>43</em><em>°</em><em> </em><em>=</em><em> </em><em>x</em><em> </em>
43 Degrees
In a instance like this one, opposite sides have the same angle measurement.
i think is B
if you want a t*-value for a 90% confidence interval when you have 9 degrees of freedom, go to the bottom of the table, find the column for 90%, and intersect it with the row for df = 9. This gives you a t*–value of 1.833 (rounded).
Hope this helps!
the same way Pythagoras Theorem
and sorry for the hand writing
a)-260
b)92
