Math question hellppp

7) An angle that measures 45° has a tangent of 1.

8) The sine and cosine ratios are equal.

9) The sine of a 30° angle is 0.5.

10) The cosine of a 30° angle is equal to the sine of a 60° angle.

Step-by-step explanation:

Question 7 explanation: In a right triangle, if one angle measures 45°, that means the non-hypotenuse sides are equivalent, so the tangent of a 45° angle is 1.

Question 8 explanation: The sine and cosine ratios of a 45° angle are always equal since the opposite and adjacent side of a right triangle will be the same length, and they both are divided by the hypotenuse.

Question 9 explanation: In a 30°, 60°, 90° right triangle, the side opposite to the 30° angle is always half the length of the hypotenuse, so the sine of a 30° angle is 0.5.

Question 10 explanation: The sine of a 60° angle is equal to the cosine of a 30° angle because the sine of an angle will always be equivalent to the cosine of its complementary angle, or the angle that results from 90° subtracted from that angle. So the cosine of a 30° angle will be equivalent to the sine of a 60° angle.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
