Solve for x in the problems below

a)1+2=90 degree

so,x+x-20=90=2x=110

x=55degree

Step-by-step explanation:

b)let it be a triangleangle1=56

2=y

3=29by vertically opposite angles

by ext angle property... x= 1+3=56+29= 85

55 degrees is the answer

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values
