Answer:
EY≅ 5.33 cm (nearest to tenth)
Step-by-step explanation:
Two triangles are said to be similar to each other if they have the same shape
(not necessarily the same size) and their corresponding sides are in
proportion
Given that,
AB = 12
DE = 8
BX = 8
ΔABC ∼ ΔDEF means that
- ∠A ∼= ∠D, ∠B ∼=∠E and ∠C ∼= ∠F.
- Further more, their corresponding sides are in proportion.
So,
12/8 = 8/EY
(by doing cross multiplication)
12EY = 8 × 8
12EY = 64
EY = 64 / 12
EY= 5.3333
EY≅ 5.33 cm (nearest to tenth)
Given: m∠A + m∠B = 90° (Definition of Complementary Angles).
Given: m∠B = (5x + 8)°
A) m∠A = 180° + (5x + 8) is your answer choice:
Why it isn't the others:
B) m∠A = 90° - (5x + 8)
You are solving for complementary angles (90° in total when combined), so you subtract the measurement for B (5x + 8) to get A.
C) m∠A = 180° - 2(5x + 8)°
You double the complementary angle to solve for the supplementary. Essentially, just divide this answer by two to get the complementary angles.
D) m∠A = 82 - 5x
I was confused by this one, but essentially they just did one step of the isolating the variable, which was subtracting 8 from both sides. They did not finish isolating the variable however.
