Answer:
24 cm
Step-by-step explanation:
Given that there is a parallelogram and adjacent sides are in the ratio
17:7
The second side =3.5cm
So we have x:3.5 = 17:7 where x is the unknown first side
Solve using ratio property to get
3.5(17) = 7x
Or x = 8.5 cm
Perimeter of parallelogram = sum of all sides
= 2(sum of one pair of adjacent sides)
=2(8.5+3.5)
=2(12)
=24 cm
Answer:
30.
Step-by-step explanation:
The 120 degree has to be the vertex angle.
The other 2 angles in the triangle will be congruent as the triangle is isosceles.
These 2 are both = (180-120) / 2
= 60/2
= 30 degrees.
