Question

The sum of 2 angles of a quadrilateral is 145. Find out each angle. The other 2 angle are in the ratio of 2:3. Find out the angles

Answer 1

Step-by-step explanation:

let the angles of quadrilateral be p, q, r &s

r=2x , s=3x

by the given condition

p+q=145

since it is quadrilateral

the sum of all angles is 360 degree

p+q+r+s=360

145+2x+3x=360

5x=360-145

5x=215

x = 215/5

x= 43 degree

r=2x=2×43=86 degree

s=3x=3×43=129 degree

Hope it helps u

Answer 2

Answer:

a,b,c,d are the angles of a quadrilateral

then given sum of 2 angles=145 °

sum of all the angles =360°

let the other two angle be 2x and 3x

therefore,

now

145+2x+3x=360

145+5x=360

5x=360-145

5x=215

x=43

therefore

one angle is 2x=2*43=86°

other angle is 3x=3*43=129°
