Answer is C (108).

All 4 angles combined are always 360 degrees. In this case if you add 2 angles combined thehy are always 180 degrees.

If we know angle 1 is 72 than angle 3 is 180-72
And 180-72 =108

3. In a certain school, there are 456 girls. Calculate the total number of students

marin [14]

Answer:

3) girls = 24% = 456

let the total number of students be = x

$\frac{24}{100} \times x = 456$

$x = 456 \times \frac{100}{4}$

$x = 1900$

the total number of students is 1900

4) increase = 20%

new salary = 24000 rupees

let his original salary be = y

$\frac{20}{100} \times y = 24000 - y$

$0.2y = 24000 - y$

$0.2y + y = 24000$

$1.2y = 24000$

$y = \frac{24000}{1.2}$

$y = 20000$

his original salary is 20,000 rupees
