Answer:
17 A...... x=56
17 B...... x=4
Step-by-step explanation:
lets start with 124
f-a is 180 degrees
we know 124 so 180-124
56 degrees under the 124
c-e is also 180 degrees
we know 6x
lets say the other degree is y
so 180=6x+y
but the y is inside the triangele, which is what we need
so the angles added up inside the triangle is
56+2x+y=180 degrees because thats what the angle measurements equal for a triangle
so 56+2x+y=180
subtract 56 from both sides
2x+y=124
divide both sides by 2
x+y=62
6x+y=180
x+y=30
124+x=180
x=56
x+y=62
56+y=62
y=6
x(56)+y(6)=62
2. problem
triangle angles must equal 180 degrees
f angle... lets say is y
so
4x+65+y=180
subtract 65 from both sides
4x+y=115
get x by itself
so -y from both sides
