Answer:
3 5/12
Step-by-step explanation:
Area of trapezoid formula:
A = 1/2(b1 + b2) h
A = 1/2(2.4 + 9)(8.2)
A = 1/2(11.4)(8.2)
A = 46.74 ml^2
Answer:
y=76 degree(being vertically opposite angle)
y+x=180 degree(being linear pair)
76+x=180
x=180-76
x=104 degree
x=z(being vertically opposite angle)
104=z
therefore z=104 ,y=76,x=104
Step-by-step explanation:
We use the law of Cosines to be able to find : 1. The measure of the
third side, when the measure of two sides and the included angle of a
triangle ABC are known. 2. The measure of any angle, when the measure of
the three sides of a triangle ABC are known.
The Law of Cosines is c² = a² + b² - 2abcosΘ. It has four variables;
a, b, c and Θ. Whenever you have a triangle with three of these
variables known, use the Law of Cosines to calculate the unknown
variable.
