The measure of the other side of a quadrilateral is cm.
In the given quadrilateral one side is unknown we need to find the unknown side.
By dividing the given quadrilateral into a rectangle and a triangle we can find the other side.
<h3>What is Pythagoras theorem?</h3>
The Pythagoras theorem states that if a triangle is right-angled, then the square of the hypotenuse is equal to the sum of the squares of the other two sides. That is, .
Now,
⇒
Therefore, the measure of the other side of a quadrilateral is cm.

3xy + 10xy - 5x + 2x - 2yx
Add 3xy to 10xy
13xy - 5x + 2x - 2yx
Add -5x to 2x
Final Answer: B.) 13xy -3x - 2yx
Answer:
Step-by-step explanation:
a + c = 257
12a + 8c = 2576
-12a - 12c = -3084
12a + 8c = 2576
-4c = -508
c = 127 children tickets
a + 127 = 257
a = 130 adult tickets
Answer:
18 cm = 180 mm
Explanation:
18 cm • 10 cm (in one mm) = 180 mm
Answer:
a1 = 4
a2= -2
a3 = -8
a4= -14
a5= -20
Step-by-step explanation:
a12= a1 + 11d
-62 = 4 + 11d
-62-4 = 11d
-66= 11d
d =
= -6
a1 = 4
a2 = 4 - 6 = -2
a3 = 4 - (6×2) = -8
a4 = 4 - (6×3) = -14
a5 = 4 - (6×4) = -20
