 Suppose the degree of a tangent to a plane is 5.67. If it’s a right angle, the measure of the degree of the tangent is the angle between the two straight lines passing through the point of the tangent.

## Answer choice B: 52.5 degree

Identifying an isosceles right triangle is a great way to learn about a math concept. The “not drawn to scale” notation is especially helpful when attempting to identify an isosceles right triangle. For example, what are the angles of a triangle if you are looking for the side XY and side YZ? A triangle with sides XY and YZ is an isosceles right triangle.

The SAT tests the wits of its students with a variety of math questions, including the ones above. This question can be solved in the traditional manner or by answering the question first, then doing the math. A little bit of math is always better than no math at all, and you will have a better chance of doing well in the SAT if you practice a few times before sitting for the test.

## Answer choice C: 63 degree

Choosing an answer choice C: 63 degree of an angle whose tangent is 5.67 is a great choice for this problem. You need to figure out how long side a is and which segment of side a meets side c in a right angle. If you use the half angle formula, you will find that the angle between the two sides of the bed is 22 degrees and that side a is 6.0 miles long. You can also use the fractional formula, which gives you the fraction of the angle that the top and bottom meet. It can be cleaned up by multiplying the top and bottom by 2 – 2.

Using the formula, you will find that the tangent to the angle is 5.67 degrees. However, you can also calculate the tangent using the half angle formula. You can also calculate the tangent using the formula by dividing the sine by the cosine.
