The sine of an angle is equal to the cosine of the complementary angle.
That is; sin r = cos 90 -r , where r is an acute angle
Therefore;
sin 73 = cos (90-73)
sin 73 = cos 17
Hence the value of r = 17
Answer:
The first five terms in the pattern are 56, 59, 62, 65 and 68.
Step-by-step explanation:
Here, the first term in the pattern = 56
Rule : Add 9, Subtract 6
Second term :
First term + 9 - 6 = 56 + 9 - 6 = 59
Third Term :
Second term + 9 - 6 = 59 + 9 - 6 = 62
Fourth Term :
Third term + 9 - 6 = 62 + 9 - 6 = 65
Fifth Term :
Fourth term + 9 - 6 = 65 + 9 - 6 = 68
Hence, the first five terms in the pattern is 56, 59, 62, 65 and 68.

The slope should be m = 2.
To find the slope you use to points and the slope formula which is (y2 - y1) / (x2 - x1).
Using two of the points you will get the slope of 2.
