Question

find the angles COD DOE COE and EOF​

Answer 1

we know that the sum of all angle is 360°

COD + DOE + EOF + EOF =360°

(2x-5)° +(x-5)°+4x°+(3x+20)=360

2x+x+4x+3x-5-5+20=360°

7x+10=360

7x=360-10

x=350÷7

x=50

now we will find the value of x

COD=(2x-5)°

=2×50-5

=95°

DOE=(x-5)°

=50-5

=45°

COE=(2x-5)°+(x-5)°

=(2×50-5)+(50-5)

=95+45

=140°

EOF=4x

=4×50

=200°
