trigonometry and area 10 5
e included angle is known or can be determined. The area can then be calculated as: \[ \text{Area} = \frac{1}{2} \times 10 \times 5 \times \sin \theta \] If the angle between the sides is 90°, then: \[ \text{Area} = \frac{1}{2} \times 10 \times 5 \times 1 = 25 \] If the an
