<u>Answer-</u>
- YZ = 9 cm

- XZ is the longest segment in triangle XYZ.
<u>Solution-</u>
Triangle XYZ is a right angle triangle with ∠Y=90°
Triangle XYZ is also an isosceles triangle, as
∠X =45°= ∠Z
Therefore, triangle XYZ is a right angle isosceles triangle.
So,
XY = YZ = 9 cm
Applying Pythagoras theorem,

In a right angle triangle, always the hypotenuse is the largest. So XZ is the longest segment in triangle XYZ.
Answer: 
Step-by-step explanation:
Given: The weight of cement = 3 tons
The weight of bricks = 150 pounds
We know that 
Therefore, 
Now, the total weight of load in truck = 
Hence, the truck's load weigh in total = 6,150 pounds.
Answer:
y = 4x + 6
Step-by-step explanation:
y = mx + b
y = 4x + b
-2 = 4(-2) + b
-2 = -8 + b
b = 6
y = 4x + 6
