The measure of ∠jlm is 140°. the measure of ∠jkl is 75°. what is the measure of ∠kjl? enter your answer in the box. ° a triangle j k l. side k l is the base. a ray extends through vertex l in horizontal direction and passes through a point labeled as m.

∠KJL is 65

Step-by-step explanation:

∠JLM + ∠JLK = 180°

140° + ∠JLK = 180°

∠JLK = 180° - 140°

∠JLK = 40°

∠JLK + ∠JKL + ∠KJL = 180°

75° + 40° + ∠KJL = 180°

115° + ∠KJL = 180°

∠KJL = 180° - 115°

∠KJL = 65°

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
