Answer:
We can represent a number in general by x . Halving a number means dividing it by two, so the expression that shows the half of a number is x2 , since you divide a number by two.
Step-by-step explanation:

Answer:
Its either answer one or two. I believe it's answer one.
Answer:
1. H = 29 cm
2. θ = 44°
Step-by-step explanation:
1. We can find the height of the triangle by considering the isosceles triangle as two right triangles. The height can be found by using Pitagoras:

Where:
L: is the sides of the isosceles triangle = 42 cm
B: is the base = 30 cm
H: is the height =?
Then, the height is:

2. The two equal angles (θ) can be found using the following trigonometric identity:


Hence, the two equal angles are 44°.
