Answer:
height = 8 cm
Step-by-step explanation:
formula to find area of a parallelogram =
base x height
so
10 x height = 80 cm square.
height = 80/10
=8 cm
We know that
in the right triangle DEF
tan F=opposite side angle F/adjacent side angle F
where
angle F=37°
opposite side angle F=DE
adjacent side angle F=FE-----> 3 units
so
tan F=DE/FE--------> DE=FE*tan F------> DE=3*tan 37-----> DE=2.26----> 2.3 units
the answer is
DE is 2.3 units
C 3 and 6 are corresponding angles
The answer is 5x+3y-3
explanation:
3x+2x+y+2y-3
= 5x+y+2y-3
=5x+3y-3
