So check the picture below
recall your SOH CAH TOA
which identity uses only
angle
opposite
adjacent?
well, is Ms Tangent.. thus
solve for "x", make sure your calculator is in Degree mode, since the angle is in degrees
Answer: 39 25/50
Step-by-step explanation:
0.78 ( 78% ) = 39/50
0.79 ( 79% ) = 39/50 + 1/2
25 is half of 50
39 25/50
<u>A. 587 * 92</u>
We are rounding these factors to the nearest ten, so 587 becomes 590 and 92 becomes 90.
Now multiply 590 and 90.
590 * 90 = 53,100; 59 * 9 = 531, and then add on the two zeroes.
The following answer of 54,004 is reasonable because it is close to our estimate of 53,100.
<u>B. 117 * 19</u>
Rounding these numbers to the nearest ten, you make 117 become 120 and 19 become 20.
Multiply 120 and 20.
120 * 20 = 2,400; I multiplied 12 and 2 to get 24, then added on the two zeroes.
The following answer of 222.3 is not reasonable because it is way off from 2,400. They are about 1,200 apart.
