Answer:
x = 14
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
x² + x² = (14
)²
2x² = 392 ( divide both sides by 2 )
x² = 196 ( take the square root of both sides )
x = 
= 14
Thus the congruent legs are 14 cm
Answer:
Distributive property
Step-by-step explanation:
the factor "3" which appears outside the parenthesis multiplies the two terms inside it. You perform the multiplication term by term. It is also referred to as the factor "3" distributes among the terms inside the parenthesis, multiplying each.
Square foot is 12 inches x 12 inches which is 144 inches so it would be 1/144
The sum of the exterior angles of the triangle is 360
The sum of the exterior angles of the quadrilateral is also 360
The sum of the exterior angles of the pentagon is again 360
Each of the shapes has an exterior angle sum of 360
