Answer:
They are proportional
Step-by-step explanation:
becaue the length of one of the square's sides is 1/4 the perimeter
<em><u>The common difference d is </u></em>
<em><u>The first term is</u></em>
<em>so , the first term is -13 </em>
This is simple division to do this you must know you multiplication. However the answer is 28 ;)
Answer: Because 7 8 9
Step-by-step explanation:
Step-by-step explanation:
since we are required to find side |BC| and the value of side |AB| is given as 6.3 cm
hence we find the cosine of the given angle...
cos71 = adjacent ÷ hypotenuse
cos71 = |AB| ÷ |BC|
cos 71 = 6.3 ÷ |BC|
|BC| = 6.3 ÷ 0.325
|BC| = 19.4 cm
