Answer:

x = 15.3°

Step-by-step explanation:

Trig identities:

sin(x)=\dfrac{O}{H} \ \ \ \ \ cos(x)=\dfrac{A}{H} \ \ \ \ \ tan(x)=\dfrac{O}{A}

where

  • x = angle
  • O = side opposite the angle
  • A = side adjacent the angle
  • H = hypotenuse

sin(46)=\dfrac{11}{x}\\\\\implies x=\dfrac{11}{sin(46)}\\\\\implies x=15.3

The ratio of boys to girls in a group is 4:1. If there are 33 more boys than girls, work out how many people there are in total.
MissTica

Total number of people is 55

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

Step 1:

Given ratio between boys and girls is 4:1. Let number of girls be x, so number of boys = 33 + x

⇒ 4x + x = x + 33 + x

⇒ 5x = 33 + 2x

⇒ 3x = 33

⇒ x = 11

Step 2:

Find total number of people.

33 + 2x = 33 + 22 = 55
