Sheldon is making a steak for dinner. at first, the steak is at room temperature, 72°friday. then, he places it on the grill, where it's temperature increase at a rate of 3 1/5°f for each minutes. after ten minutes, he removed the steak from the grill and let's it cool for 7 minutes on the counter. while it is siting on the counter, it's cool at a rate of 4 2/7°f each minutes. what was the net change in the temperature of the steak from before it was cooked and when it was served?

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°

is should be y = 5x
