Answer:
A
Step-by-step explanation:
according to tangent property
we get
Given that
Thus our equation is

substitute the given values

simplify multiplication:

simplify addition:

cancel 20 from both sides:

divide both sides by 2:

AN=CN
hence,CN=7
therefore our answer is A

64 cm2 C.
Step-by-step explanation:
Hope this helps you :)
When all sides of a quadrilateral are equal (indicated by tick marks on the four sides) in length and connect the opposing vertices with a line, it will form four 90° angles. Therefore, each equation will equal 90.
10x= 90
x+y= 90
3z= 90
The measure of angles 1 and 3 can be solved as they are so:
10x= 90 ➡️ x=9
3z= 90 ➡️ z= 30
The value of x is needed to solve for the measure of angle 2 so plug in the value of x and solve:
x+y= 90
9+y= 90
y= 81
Therefore the answer is a.
Answer:
A
Step-by-step explanation:
If You have 9/4 then you have to go backwards and that means subtracting everything you have to get to 0. that means you take away what you have which is 9/4.
