Find the angles ​

Answer 1

Answer:

the first angle is 86 and the second one is 129

Step-by-step explanation:

its fully correct

Answer 2

Answer:

I am good in maths but I tried to slove it

Step-by-step explanation:

the sum of angles of quadrilateral = 360 degree

let's be the angle, so 2:3 = 2a :3a ------------ (1)

given A + B + C + D = 360 degree and A+B = 145 I.e

= 145 + 2a + 3a = 360 degrees

a = 215/5 = 43 degree

submit the value in 1

we get the remaining value 86 degrees and 129 degrees

so C = 86 degrees

D = 129 degrees //
