Answer:
x = 135º
Step-by-step explanation:
Sum of angles in a triangle is 180
A = 180 - 66 - 69
A = 45º
--------------------
Supplementary angles total 180
x = 180 - 45
x = 135º
Answer:
y=50x+200 can i get the brainliest?
Step-by-step explanation:
Answer:
x = 75 degree
Step-by-step explanation:
Angle between C and B must equal 90 degree.
90- 15 equal 75 degree.
Knowing this angel C and E is equal to angel F and D
Answer:
Step-by-step explanation:
sin(7y)=cos(5y+14)=sin(90-(5y+14))=sin(76-5y)
7y=76-5y
12y=76
y=76/12=19/3
or
sin(7y)=cos (5y+14)=sin (90+(5y+14))=sin (5y+104)
7y=5y+104
2y=104
y=52
