Answer:
Option D is correct.
XY = 10 cm
Step-by-step explanation:
Complete Question
Which of the following statements must be true, given that ABC = XYZ and AB = 10 cm?
The diagram for the question is missing.
Solution
The diagram for the question isn't attached.
But from the condition, ABC = XYZ, it is evident that the two triangles are similar according to the SSS congruent theorem.
If all three pairs of corresponding sides of two triangles are proportional, then the two triangles are similar. And from the condition given, we can predict, without seeing the diagram for the question, that
(AB/XY) = (BC/YZ) = (CA/ZX)
We can also predict that the triangles are exactly the same and the proportionality bbetween is 1.
AB = XY
BC = YZ
CA = ZX
Hence, AB = XY = 10 cm.
Hope this Helps!!!
Answer: there are 8 quarters in the jar
Step-by-step explanation:
Let x represent the number of nickels that is inside the jar.
The total number of coins inside the jar is 20.
Probability is expressed as
Number of possible or favorable outcomes/total number of outcomes.
The probability of selecting a nickel is 0.6. This is expressed as
0.6 = x/20
Cross multiplying, it becomes
x = 20 × 0.6
x = 12
Since there are 12 nickels inside the jar, then the number of quarters would be
20 - 12 = 8
Answer:
∠B` = 109.73°, ∠B = 70.27°
Step-by-step explanation:
∠B + ∠B` = 180°
The Sine Law:
10 / sin B` = 9.2 / sin 60°
10 / sin B` = 9.2 / √3/2
sin B` = 0.94133
B` = sin^(-1) 0.94133
∠B` = 109.73°, ∠B = 70.27°
