Answer:
Step-by-step explanation: x+ 48+ 20 =180 (sum of all angles in triangle)
x+ 68 = 180
x= 180-68
x= 112
x + y = 180 (linear pair axiom)
112 + y = 180
y = 180-112
y = 68
(thanks later)
x=22
y=20
Step-by-step explanation:
firstly we know in triangle ACB
angle b =48+20=68
angle c= 90 (given)
Now to find angle x
we know all the angles in the triangle add upto 180
therefore angle a +angleb+angle c =180
a+68+90=180
a=180-158
a=22
so angle x is 22 degrees
In triangle ADB
angle a=x+y
angle b=48
angle d=90
a+b+c=180
x+y+48+90=180
22+y+48+90=180
22+138+y=180
y=180-160
