ΔABC is similar to ΔXYZ with a ratio of similitude of 8:3. Also, XZ is 1 less than AB and BC is 4 more than AC. If XY=9, what is YZ?

In the Isosceles Triangle ABC,

∠BAC = 30°

So,

∠CBA also = 30° = x (Opposite side in a Isosceles ∆)

_____________________________________

If ∠BAC & ∠CBA = 30°

Then,

∠BAC + ∠CBA + ∠ACB = 180° (Angle Sum Prop. of a Triangle)

➠ 30° + 30° + ∠ACB = 180°

➠ ∠ACB = 180° - 60°

➠ ∠ACB = 120°

If ACB = 120° Then,

∠BCD = 180° - 120°

∠BCD = z = 60°

___________________________________

If z = 60°

Then,

Y also = 60° (Opp. Sides in an Isosceles ∆ )

____________________________________

Overall,

x = 30°

y = 60°

z = 60°

300

step-by-step explanation:

28-600w < 300

28-600w > 300

600-28w < 300

600-28w > 300

it would be:
