Answer:
120 degrees
Step-by-step explanation:
As we know, the exterior angle of a triangle is equal to the two opposite interior angles, in this case,
JKL = JHK + HJK
=> JKL = 24 + 96
=> JKL = 120 degrees

Answer:
32.5
Step-by-step explanation:
its a trick question
Step-by-step explanation:
when intersecting 2 parallel lines by a third line the angles at the intersection points must be the same at both lines. otherwise they are not parallel, or the third one is not a straight line.
the second thing to know : all angles in top of a line (or below a line) are in sum 180 degrees. this is what is needed to e.g. rotate a stick around a point on the line from one side to the other.
knowing all this we then know, that the angle right "under" the (8x -9) degree angle is also 53 degrees (or the angle above the 53 degree angle is (8x - 9) degrees).
and we know then that the sum of both angles is 180 degrees.
(8x - 9) + 53 = 180
8x - 9 = 127
8x = 136
x = 17
Answer:
c = 34/d
d = 1/2
Step-by-step explanation:
Part A
Basic Formula
c = k/d
17 = k/2 Multiply both sides by 2
17*2 = k*2/2 Combine
34 = k
So the equation is c = 34/d
Part B
c = 68
k = 34
d = ?
68 = 34/d Multiply both sides by d
68*d = 34 * d/d Simplify.
68 d = 34 Divide by 68
d = 34/68 Simplify
d = 1/2
