From the figure , it is quite clear that the sides AB and AC have the same measure , i.e. , 8 units .
we know that ,
angles opposite to equal sides are equal.
therefore ,
∠B = ∠C = 30°
Now ,
angle sum property of a ∆ states that the sum of all the angles of a triangle equals 180°
thus ,
therefore ,
option ( c ) 120° is correct .

Step-by-step explanation:
Answer:
Height = 5 and Base = 10
Step-by-step explanation:
The base of the parallelogram is twice the perpendicular height of the parallelogram. The area of the parallelogram is 50 cm².
Formula for area of parallelogram = base × height
Base = 2h
Height = h
∴ Area = 2h × h = 50
Solution:
2h × h = 50
2h² = 50
h² = 25
h = 5
∴ height = 5 and base = 2(5) = 10
2(9x+12) + 2(3x-4)
because there are four sides, and it is a parallelogram, the opposite sides are equal. the answer is 24x+16
