Answer:
a)
Step-by-step explanation:
Square root of 75 (√75) is regarded as a surd function because the value inside the square root sign is not a perfect square. In that case the given value will be splitted into the product of a largest perfect square and a prime number as shown:
√75 = √3×25
√75 = √3×√25
√75 = √3 × 5
√75 = 5√3
a) Based on the above calculation, it can be inferred that his reasoning is incorrect. The value of 3 was supposed to be inside a square root not a whole number i.e √3 × √25
b) Since √75 = 5√3
√75 = 5 × 1.7321
√75 = 8.6605
√75 = 8.661 {to nearest thousand}

Step-by-step explanation:
AB ≅ BC (because median cuts a line segment into two equal (congruent ≅) parts
Set up your equation now:
3 - 2x = x - 12
3 + 12 = 2x + x
15 = 3x
15/3 = x
5 = x

Answer:
23.6 degrees
Step-by-step explanation:
Here, sin(<XZY) = 6/15 = 2/5
So, <XZY = arcsin(2/5) = 23.6
