Answer:
See explanation.
Step-by-step explanation:
To find the area of a parallogram, do A=Bh where a is the area, b is the base, and h is the height.
In this case, b is 9 cm while h is 6 cm. Do A=Bh by multiplying 9 cm by 6 cm. This will give us 54 cm².
The measurement we didn't use is the measure of the diagonal parts of the quadrilateral which, in this case, was 7.5 cm.
Answer:
Use the cosine rule
Step-by-step explanation:
1. Apply formula of c^2 = a^2 + b^2 - 2abcosC
2. Substitute known values in: c^2 = 36 + 4900 - 840cos120
3. Apply algebra and use the calculator
4. Final answer is 73.18 (2 decimal places)
Answer:
x = 2
Step-by-step explanation:
AC = BC
5x = 10
x = 2
Answer:
D.
Step-by-step explanation:
a² -b²= (a-b)(a+b)
100x²-49y²= (10x-7y)(10x+7y)
Answer:
Equation of tangent will be 
Step-by-step explanation:
We have given the function 
We have to find the equation of tangent at the point 
Equation of tangent is equal to 
So 
Now we have given point
So putting these points in the equation of tangent
Now equation of tangent passing through
