Answer:

a=8.06

A=29.74

B=60.26

Step-by-step explanation:

This is a right angled triangle and Pythagoras theorem is to be obeyed.

To get c, we follow the Pythagoras rule that says

Hyp² = Opp² + Adj²

c= Hypotenuse

c²= a² + b²

c² = 4² + 7²

c² = 65

c = √65 = 8.06

For angle A,

the opposing side to the angle = a = 4

The adjacent side to the angle = b = 7

Following trigonometry rule.

Tan A = opp/adj

Tan A = 4/7

A = Tan–¹(4/7)

A = 29.74°

For angle B,

Opposing side = 7

Adjacent side = 4

Tan B = 7/4

B = Tan-¹(7/4)

B = 60.26°

<u>Answer:</u>

  • $2,800 = Principle + Interest

<u>Step-by-step explanation:</u>

Using PRT/100, let's find the interest.

  • => 2,000 x 8 x 5/100
  • => 20 x 8 x 5
  • => $800

<u>Conclusion: </u>

Therefore, the interest plus principle is 2,000 + 800, which is $2,800.

Hoped this helped.
