Answer:
b= 0.9
Step-by-step explanation:
first you find angle B: 180-90-25=65
then you will do law of sine- sin A/a=sin B/b=sin C/c
sin(90)/1=sin 65/b
sin(90)*b=sin(65)*1
sin(90)*b=0.9
b=0.9/sin(90)
b= 0.9
Yo sup??
Area of trapezium=1/2*(sum of opposite sides)*(height of trapezium)
=1/2*(12.5+17.5)*6
=1/2*30*6
=90 cm²
