to create AA'B'C' with ZA' =
For AABC, ZA = 2x - 2, 2B - 2x + 2, and 2C = 5x. If AABC undergoes a dilation by a scale factor of
58 - X, ZB' = 3x - 18, and C = 120 - X, which confirms that AABCAA'B'C by the AA criterion?
ZA - ZA' = 38 and 2B - ZB' = 42
ZA = ZA = 19* and ZC = 20 = 21
ZB = ZB' = 18 and 2C -
C = 50°
ZB - ZB' = 32 and 2C = 2C = 75°

step-by-step explanation:

i believe the answer is letter c) 8

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°
