Answer:
x= 30 degrees
Step-by-step explanation:
This is an isosceles triangle as indicates by the lines on the sides.
Since the sides lengths are equal, the base angles are equal
x= 30 degrees
9)

10) The y-intercept is always the constant term (without

). Therefore, the y-int is -9. The slope is always the term in front of the

, and so it is 3.
Answer: 64 cm ²
Step-by-step explanation:
The perimeter of this rectangle will be:
= 2 * Length + 2 * Width
= 2 * 10 + 2 * 6
= 20 + 12
= 32 cm
The square has the same perimeter. Squares have 4 equal sides so each side of the square must be:
= 32 / 4
= 8 cm
Area = Length * Width
= 8 * 8
= 64 cm ²
