Solve the right triangle. Round decimals to the nearest tenth
Tems11 [23]

Answer:

  j = 19.6

  k = 25.9

  J = 49°

Step-by-step explanation:

The mnemonic SOH CAH TOA is intended to remind you of the relationships between sides and angles in a right triangle.

<h3>Analysis</h3>

The given side is opposite the given angle. We want to find the other acute angle and the missing sides: the hypotenuse, and the adjacent side. The relations involving the opposite side are ...

  Sin = Opposite/Hypotenuse   ⇒   Hypotenuse = Opposite/Sin

  Tan = Opposite/Adjacent   ⇒   Adjacent = Opposite/Tan

Of course, the acute angles in a right triangle are complementary, so we can use that fact to find the missing angle.

<h3>Application</h3>

  Hypotenuse = Opposite/Sin

  IJ = 17/sin(41°) ≈ 25.9

  Adjacent = Opposite/Tan

 IK = 17/tan(41°) ≈ 19.6

  Angle J = 90° -41° = 49°

In summary, ...

  j = 19.6

  k = 25.9

  J = 49°

If a work group consistently achieves 80 % of its quarterly goals and the work group generally has 25 objectives per quarter how
storchak [24]
What this question is asking you to find 80% of 25. 10% of 25 is 2.5 because there is always a decimal point directly to the right of the ones place. (25.0)
You would move the decimal point over one place to find 10% of a given number. How I would approach this is to multiply 2.5 by 8 to find 80% of 25

2.5 x 8 = 20

80% of 25 = 20

You can expect the work group to get done 20 out of 25 of their objectives per quarter
