Answer:
¹/25 mm²
Step-by-step explanation:
Area of a square = s²
Where s is the length of one side
using the diagram given,
s = ⅕ mm
Area = (⅕)²
Area of the square = ¹/25 mm²
15cm if it’s a right triangle
Both equations are the same angle so you have to create your own equation to solve for x.
4x + 66 = 7x + 15
Subtract 4x to both sides.
66 = 3x + 15
Subtract 15 from both sides.
51 = 3x
Divide.
17 = x
