Answer:
49
Step-by-step explanation:
side 1 = |18-3|= 15
side 2 = |12-3| = 9
side 3 = |16-4| = 12
side 4: 
perimeter = 15 + 9 + 12 + 13,4= 49,4 = 49
3.65 e8
Step-by-step explanation:
The scientific notation e mean ‘10 raised to a particular power’. Therefore e8 is equivalent to 10 ^ 8.
We count the number of tens to the decimal point. In this case;
365000000
3.65000000
The decimal is <u>8</u><u> place values </u>from the right (since this is a whole number)
Step-by-step explanation:
tan 60 = 21 ÷ y
1.73 = 21 ÷ y
y = 21 ÷ 1.73
y = 12.14
tan 30 = x÷ 12
0.6 x 12 = x
x = 7.2
The answer is C : x = 2 rad 2 and y= 2 rad 3
