Which of the following tables shows the correct steps to transform x2 + 6x + 8 = 0 into the form (x − p)2 = q? [p and q are integers] A. Step 1 x2 + 6x + 8 − 1 = 0 − 1
Step 2 x2 + 6x + 7 = −1
Step 3 (x + 3)2 = −1
B. Step 1 x2 + 6x + 8 + 1 = 0 + 1
Step 2 x2 + 6x + 9 = 1
Step 3 (x + 3)2 = 1
C. Step 1 x2 + 6x + 8 − 2 = 0 − 2
Step 2 x2 + 6x + 6 = −2
Step 3 (x + 3)2 = −2
D. Step 1 x2 + 6x + 8 + 2 = 0 + 2
Step 2 x2 + 6x + 10 = 2
Step 3 (x + 3)2 = 2

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°
