Answer 1

Answer:

$\huge \green{\fbox { \fbox{{\: answer : }}}}$

$\huge{ \sf{{ \underline{formula \: used : }}}}$

$\bf \purple\bigstar{(n - 2)} \times 180 \degree$

$\purple\bigstar \bf{(n) \: be \: the \: number \: of \: sides}$

$\huge{ \sf{{ \underline{\: solution : }}}}$

$\bf(3 - 2) \times 180 \degree$

$\to\bf(3 - 2) \times 180 \degree$

$\to\bf(1) \times 180 \degree$

$\bf \to180 \degree$

Answer 2

Answer:

Angle of equilateral triangle(taken for simplicity), the sum of all angles if 180

Step-by-step explanation:

Reason::: The angles are equal (in this case = 60), so we multiply the angles by 3 as we have corners where we can make angles

The answer= 60 x 3 = 180.
