The lengths of the boards are 6 cm and 8 cm.
The boards make a right angle.
Therefore the string connecting the boards is the hypotenuse of a right triangle (shown n the figure).
By the Pythagorean theorem,
c² = 6² + 8² = 100
c = 10 cm
Answer: c = 10 cm
Answer:
A coordinate system is a two-dimensional number line, for example, two perpendicular number lines or axes. The center of the coordinate system (where the lines intersect) is called the origin. The axes intersect when both x and y are zero. The coordinates of the origin are (0, 0).
X/y
- 8/20=42/y
- 0.4=42/y
- y=42/0.4
- y=105

Answer:
Opposite sides are congruent
Step-by-step explanation:
you can create equations -18 + 7x = 3x + 14 and 13y = 9 + 10y to solve for x and y to find the length of each side and whether they(the two pairs of opposite sides) are congruent or not
