Answer 1

Answer:

SUM OF ALL ANGLES OF QUADRILATERAL IS 360 DEGREES.

SO,

$q1. \: let \: the \: fourth \: angle \: be \: x \\ so \: 80 + 80 + 80 + x = 360 \\ 240 + x = 360 \\ x = 360 - 240 \\ x = 120 \\ so \: the \: fouth \: angle \: is \: 120 \: degree.$

Step-by-step explanation:

$q2. \: \: a = b = c \\ so \: let \: these \: three \: angles \: be \: x \: \\ 150 + x + x + x = 360 \\ 150 + 3x = 360 \\ 3x = 360 - 150 \\ 3x = 210 \\ x = \frac{210}{3} \\ x = 70$
