How many birthday cakes can Mark make in 5 days?
birthday cakes

30

Step-by-step explanation:

If Mark can make 42 birthday cakes in 7 days that means he can make 6 cakes a day. Multiply this by 5 and you get 30

30 cakes

Step-by-step explanation:

42 divided by 7 is 6 so the math you would do is 5 times 6 which 30 and the subject is cakes do the answer is 30 cakes.

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°
