Answer:
4
Step-by-step explanation:
g(3) = -2(3)^2 -4 = 2(9) -4 = 18-4 = 14
|f(2)| = | 2^2 -3| = | 4-3| = 1
(g(3) +2) = (14+2) = 16
4* |f(2)| = 4*1 = 4
16/4 = 4
Given:
The parallel sides of a trapezium are 28.7 cm and 22.3 cm.
The distance between parallel sides is 16 cm.
To find:
The area of a trapezium.
Solution:
The area of the trapezium is:

Where,
are parallel sides and
is the vertical distance between the parallel sides.
Putting
in the above formula, we get




Therefore, the area of the trapezium is 408 square cm.
Answer:12.1
Step-by-step explanation:
Angle D=180-(82+52)
Angle D=180-134
Angle D=46
Using sine rule
e/sinE=d/sinD
e/sin52=11/sin46
e/0.7880=11/0.7193
e/0.7880=15.29
Cross multiply
e=15.29 x 0.7880
e=12.05
e=12.1 approximately
