Question

side =8 cm a acute angle between one pair of side is 30degree find its area

Answer 1

Value of any side = 8cm
value of an interior angle = 30
Area of rhombus = (side²)*sin a = 64*sin 30
= 64*0.5
therefore the area of rhombus is 32 cm²

Answer 2

Area will be 16 square units.

Step-by-step explanation:

The sides are 8 cm each and including an angle between those sides is 30°. Now we have to find what will be the area of the triangle.

Now, we know the formula from properties of the triangle, of the area of a triangle which is given by

Δ = $\frac{1}{2} \times b\times c \times \sin A$

Hence, Δ = 0.5 × 8 × 8 × Sin 30° = 16 square units. (Answer)
