Answer:
It has exactly 4 faces that triangles.
Step-by-step explanation:
Answer:
130 degrees
Step-by-step explanation:
7 and 2 are alike.
Area = 1/2 x (a+b) x h
= 1/2 x ( 5+ 13) x 17
=1/2 x 18 x 17
= 153cm.
(a and b are the two parallel lines. H is height.)
Answer:
50 degrees.
Step-by-step explanation:
Angle FGE =
because angles on a straight line add up to 180 degrees.
Angle EFG =
(Angles in a triangle add up to 180)



Add 20 to both sides:


Subtract 6x from both sides:


Angle 
32% of 60
32% × 60
0.32 × 60
19.2
