To answer the problem above, I assume that the four-sided figure has equal measure of the sides. Let x be the lengths of each side and the equation for the perimeter is,
P = 4x
Substituting the known values,
70 in = 4x
The value of x is 17.5 in.
Therefore, the each side of the quadrilateral is 17.5 inches long.
Answer:
12x + 15 = 12x - 15
Step-by-step explanation:
-5x - 25 = 5x + 25
-25 = 10x + 25
-50 = 10x
-5 = x
12x + 15 = 12x - 15
15 = -15 ( No solution )
12x + 15 = 3(4x + 5)
12x + 15 = 12x + 15
12x = 12x
0 = 0 ( True for all x's )
7x + 21 = 21
7x = 0
x = 0
Answer:
h=20
Step-by-step explanation:
h=3 (V/lw)
h= 3 (960/12*12)
Answer:
The statement which justifies Andrea's statement is "Corresponding angles are congruent" ⇒ C
Step-by-step explanation:
If two parallel lines intersected by a line, then there are some pair of angles are formed
- Corresponding angles that are congruent
- Alternate interior angles that are congruent
- Alternate exterior angles that are congruent
- Consecutive interior angles that are supplementary
In the given figure
∵ Lines l and m are parallel
∵ They are cut by transversal p
∵ ∠2 and ∠3 are in the corresponding position
→ By using the 1st rule above
∵ Corresponding angles are congruent
∴ ∠2 ≅ ∠3
∴ m∠3 = m∠2
∵ m∠2 = 40°
∴ m∠3 = 40°
The statement which justifies Andrea's statement is "Corresponding angles are congruent"
