Question

Four angles of a quadrilateral ABCD are 4y + 20°, 3y -5°, 4x and 7x +5° respectively, find the angles.​

Answer 1

Answer:

$4y + 20 = 360 \\ 4y = 360 - 20 \\ 4y = 340 \\ y = 85 \: is \: the \: first \: angle \\ 4x = 360 \\ x = 360 \div 4 \\ x = 90 \: is \: the \: second \: angle$

Step-by-step explanation:

1st angle is 90 and second angle is 85 and third angle is85 and 4rth angle is 90
