Someone me and my crew on this! we rlly needus
given: lines jm and ln.
find the measure of the following angles.
m∠lpm=
degrees.
m∠mpn=
degrees.
m∠kpj=
degrees.

answer:

angle lpm is 38 degrees

angle mpn is 142 degrees

angle kpj is 52 degrees

step-by-step explanation:

as you can see, angle kpl is a 90 degree angle, and angle npj is 38 degrees. angle npl is a 180 degree angle. so all you would do is add 90 and 38 then subtract 180 from that, to get angle kpj.

90 + 38 = 128

180 - 128 = 52

now that you found angle kpj, you can add its angle degree (52) to the 90 degree angle (kpl) to find angle lpm.

52 + 90 = 142

180 - 142 = 38

then to find angle mpn, all you need to do is subtract 180 from angle jpn, which is 38 degrees

180 - 38 = 142

answer:

mlpm: 38 degrees

mmpn: 142 degrees

mkpj: 52 degrees

step-by-step explanation:

first you have to figure out what mkpj is to get the rest:

so, ln is a 180 degree angle, and you minus the right angle or the square, (90 degrees), and the 38 degree angle, and you would get 52 degrees. this means that mkpj is 52 degrees at an angle.

next you have to do mlpm and now you know the other angles so what you do is that, you know that jm is also another 180 degree angle, and you would add the other two angles, which are 52 and 38 degrees together then minus it by 180 degrees and you get 38 degrees. this means that mlpm is 38 degrees at an angle.

last but not least, mmpn angle, now what you do is that you know jm is 180 degree angle and you add the 52 and 90 degree angle and then minus then by the 180 and you get 142 degrees. this means that mmpn is 142 degrees at an angle.

hope this , good luck on your guys test! : )

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
