Answer:
42°
Step-by-step explanation:
3x + 54° = 180° [Supplementary angles]
=> 3x = 180 - 54
=> 3x = 126
=> <u>x = 42</u><u>°</u><u> </u><u>(Ans)</u>
Alright, so let's make the length x and the width y. 2y=x, and xy=area. 2x+2y=perimeter. Plugging 2y=x into the perimeter equation, we get that 3x=perimeter=126, and x=126/3=42
Length=42ft, width=21ft
Since everything is half off, you save half of your money or %50.
Answer:
Step-by-step explanation:
You need to set up a proportion
Let x = NK
7/13 = x/56 Notice that the longest side of the small trapezoid is the denominator of the fraction on the left. That means that the longest side of the large trapezoid must also be the denominator of that fraction on the right.
Cross multiply
13x = 7*56 Combine the right
13x = 392 Divide by 13
x = 392/13
x = 30.15
NK = 30.15
Yes, it is true.

For example,
take two integers 12 and 4
12 × 4 = 48 : product is positive
12 ÷ 4 = 3: quotient is positive
____________________
If you take -12 and 4
-12 × 4 = -48 : product is negative
-12 ÷ 4 = -3: quotient is negative
