The answer is A I’m sure it’s correct
Answer:
and 
Step-by-step explanation:
The ratios of sine and cos are defined as follows:
, and

The hypotenuse is always the side opposite of the 90 degree angle (for the given triangle, the hypotenuse is 85)
Since we are looking at the angle A, the opposite side with respect to A would be the side length of 84. That leaves the side 13 as the adjacent side.
Thus, we can now write:


The correct answer is the first answer choice.
Answer:
∠ D = 127°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ D is an exterior angle of the triangle , then
∠ D = 85° + 42° = 127°
Answer:
1,500
Step-by-step explanation:
K means thousand, so the answer would be 1,500.
The answer is 88 because both numbers are fractions and you need to divide it. So you flip one of the fractions from bottom to top, in this case your next step can be 11/2 multiplied by 16. And then you divied 16 by 2 which is 8. After that you multiply 8 to 11 and that gives you 88 =)
