Step-by-step explanation:
I think this is angles topic.
related with right angles and adjacent angles.
Answer:
BXF = 75
Step-by-step explanation:
We know that CXE is a straight line
A straight line is 180 degrees
CXE = CXG + GXD +DXE
Substituting what we know
180 = 85+ GXD + 20
Combine like terms
180 = 105+GXD
Subtract 105 from each side
180-105 = 105-105 +GXD
75 = GXD
GXD and BXF are vertical angles
GXD = 75 which means BXF = 75
The sum of angles in any triangle is 180 degrees.
It is given <1+<3=154 degrees.
<1+<2+<3=180
Or <1+<3+<2=180
Substituting <1+<3=154 we have
154+<2=180
Subtracting 154 both sides <2=180-154
<2= 26 degrees
First option is right answer.
Two Angles are Supplementary when they add up to 180 degrees
Two Angles are complementary when they add up to 90 degrees
Given <1+<3 =154 So they are neither complementary or supplementary.
Answer:Neither
