Using the fact that cos of ๐ is equal to the sin of 90 degrees minus ๐, what is the equivalent to the cos of 35 degrees?
00:00:10.740 --> 00:00:12.570
So here is the equation that we will use.
00:00:12.570 --> 00:00:16.970
And we wanna find whatโs the equivalent to the cos of 35 degrees.
00:00:17.220 --> 00:00:22.830
So essentially, weโre replacing ๐, which is an angle, with 35 degrees.
00:00:23.260 --> 00:00:27.210
So we need to take 35 degrees and plug it into the other side of the equation.
00:00:27.650 --> 00:00:30.260
So weโve replaced ๐ with 35 degrees.
00:00:30.260 --> 00:00:31.240
And now we simplify.
00:00:31.790 --> 00:00:35.820
So we need to take 90 degrees minus 35 degrees.
00:00:36.150 --> 00:00:39.240
And 90 minus 35 is equal to 55.
00:00:40.150 --> 00:00:45.450
Therefore, the sin of 55 degrees is equivalent to the cos of 35 degrees.
