I'LL GIVE BRAINLIEST FASTERR

please explain how do you get the answer !​

i) 37

ii) 120

iii) 157

Step-by-step explanation:

i)

Since triangle ABD is equilateral all of its angles are 60

this means angle ACD is 60 and since BCD is a straight line BCA+ADC=180

BCA = 180-ACD

BCA=180-60 = 120

then since angles in a triangle add to 180 you know that 23+x+BCA=180

143+x=180

x=37

ii)

Since triangle ABD is equilateral all of its angles are 60

this means angle ADC is 60 and since CDE is a straight line y+ADC=180

y = 180-ADC

y=180-60 = 120

iii)

using the values from part i and ii

x+y = 120+37 = 157
