I have the are of the rectangle, but how can I find the area of the triangle?

Right hand side triangle: 2 square units

Left hand side triangle: 1.5 square units

Step-by-step explanation:

The area of a triangle is given by the equation A = 1/2 * base * height. For the left triangle, this means 1/2 * 2 * 1.5, which equals 1.5 For the right hand triangle, this is 1/2 * (8.5-4.5) * 2, which is 4.

d≈7.07in

step-by-step explanation:

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°
