Answer:
x=9.5
NMR= 18°
Step-by-step explanation:
MN bisects PMN so NMR is equal to PMN making it also 18° so with this info we can now find x
(4x-2)=36
4x=38
x=9.5

Answer:
24 cm²
Step-by-step explanation:
To find the area of the trapezium, we must know the length CD. That means we must know the length BC. Fortunately, the perimeter of ABCF is given, so we have ...
P = 2(AB +BC)
BC = (P/2) -AB = (20 cm)/2 - 6 cm = 4 cm
Then CD is ...
CD = BD -BC = 9 cm -4 cm = 5 cm
The area of the trapezium is given by the formula ...
A = (1/2)(b1 +b2)h
A = (1/2)(5 cm + 3 cm)(6 cm) = 24 cm²
The area of trapezium CDEF is 24 cm².
18333/10000
Convert to a fraction by placing the decimal number over a power of 10
You would probably find it on the altitude or height.
