Answer:
127.5
Step-by-step explanation:
First, we need to find the value of x
since the two angles are connected to a straight line, their sum will be 180 (degrees)
add the angles together
add 2 to both sides
divide out by 8
now we must determine which angle has the greater value (not visually)
so the answer would be 127.5
The answer will be B! I hope this helps!
The answer should be 1/3=12-n
Answer:
d = 9
Step-by-step explanation:
Calculate the slope m of line AB and equate the result to 3
m = 
with (x₁, y₁ ) = A(4, 6) and (x₂, y₂ ) = B(d, 21)
m = 
= 
= 3 ( multiply both sides by d - 4 )
15 = 3(d - 4), that is
15 = 3d - 12 ( add 12 to both sides )
27 = 3d ( divide both sides by 3 )
9 = d
