Answer:

sin A = opp / hyp = 0.82

Step-by-step explanation:

The sine function is defined as the ratio of "opposite side" to "hypotenuse."

In the given triangle, sin A = opp / hyp = 10.3 / 12.6 = 0.82 (to the nearest hundredth).  That's all you have to do here.

The cosine function is the ratio of "adjacent side" to "hyp."  In the given triangle, the side adjacent to angle A has length 7 .2.  Thus,

cos A = adj / hyp = 7.2 / 12.6 = 0.57 (to the nearest hundredth).

Jackson is 5 years old. His brother Micah is 20 years older than him. Which equation represents Micah's age in comparison with J
mina [271]

Answer:

M=5+20

Step-by-step explanation:

I’m using M for representing Micah’s age.

This would represent Micah’s age because it says that Micah is 20 years older than Jackson, who is 5. Therefore, you would just need to add 5 and 20 together. Micah is 25 years old.
