What is the measure of JKL?

Mathematics
2 answers:
Orlov [11]3 years ago
7 0

Answer:

97

Step-by-step explanation:

83 and JKL form a straight line so they add to 180 degrees

83+ JKL = 180

Subtract 180 from each side

83-83+ JKL = 180-83

JKL = 97

Which students line segments have a midpoint of (-1,4)? Select all that apply A. Student 1 B. Student 2 C. Student 3 D. Student
SashulF [63]

Answer:

C. Student 3

E. Student 5

Step-by-step explanation:

we know that

The formula to calculate the midpoint between two points is equal to

M(\frac{x1+x2}{2},\frac{y1+y2}{2})

<u><em>Verify the midpoint of each student</em></u>

student 1

we have the endpoints

(-9,0) and (11,-8)

substitute in the formula

M(\frac{-9+11}{2},\frac{0-8}{2})

M(1,-4)

so

The midpoint is not (-1,4)

student 2

we have the endpoints

(-6,-1) and (4,-7)

substitute in the formula

M(\frac{-6+4}{2},\frac{-1-7}{2})

M(-1,-4)

so

The midpoint is not (-1,4)

student 3

we have the endpoints

(-5,2) and (3,6)

substitute in the formula

M(\frac{-5+3}{2},\frac{2+6}{2})

M(-1,4)

so

<u>The midpoint is equal to (-1,4)</u>

student 4

we have the endpoints

(-3,10) and (5,-2)

substitute in the formula

M(\frac{-3+5}{2},\frac{10-2}{2})

M(1,4)

so

The midpoint is not (-1,4)

student 5

we have the endpoints

(0,-3) and (-2,11)

substitute in the formula

M(\frac{0-2}{2},\frac{-3+11}{2})

M(-1,4)

so

<u>The midpoint is equal to (-1,4)</u>

therefore

Student 3 and student 5

Line JM intersects line GK at point N Which statements are true about the figure? Check all that apply.
Likurg_2 [28]

we know that

Complementary angles are two angles whose sum is equal to 90°, while supplementary angles are two angles whose sum is equal to 180°.

So

Statements

case 1) GNJ is complementary to JNK

Is False

Angle GNJ is 90 degrees and angle JNK is 90 degrees. The sum of the angles GNJ and JNK is 180 degrees. Therefore, GNJ is not complemetary to JNK.

angle\  GNJ+angle\  JNK=180\  degrees

GNJ is supplementary to JNK, not complementary

case 2) MNL is complementary to KNL

Is True

The sum of angles MNL and KNL is MNK which is 90 degrees. Therefore, MNL is complementary to GNJ.

angle\  MNL+angle\  KNL=90\  degrees

MNL is complementary to KNL

case 3) MNG is complementary to GNJ

Is False

Angle MNG is 90 degrees and angle GNJ is 90 degrees. The sum of the angles MNG and GNJ is 180 degrees. Therefore, MNG is not complemetary to GNJ.

angle\  MNG+angle\  GNJ=180\  degrees

MNG is supplementary to GNJ, not complementary

case 4) KNJ is supplementary to MNL

Is False

Angle KNJ is 90 degrees and angle MNL is less than 90 degrees. The sum of the angles KNJ and MNL is less than 180 degrees. Therefore, KNJ is not supplementary to MNL

angle\ KNJ+angle\  MNL < 180\  degrees

case 5) GNM is supplementary to JNK

Is True

Angle GNM is 90 degrees and angle JNK is 90 degrees. The sum of the angles GNM and JNK is 180 degrees. Therefore, GNM is supplementary to JNK.

angle\ GNM+angle\  JNK = 180\  degrees

GNM is supplementary to JNK

therefore

the answer is

MNL is complementary to KNL

GNM is supplementary to JNK

In Triangle ABC, the length of Segment AB is equal to the length of segment AC. The length of segment BC is 4 less than twice th
seraphim [82]

Step-by-step explanation:

Let x be the length of segment AB.

Then the length of segment BC is (2x - 4).

The length of segment AC is x.

We know that x + (2x - 4) + x = 52.

Therefore 4x - 4 = 52, 4x = 56, x = 14.

Hence the length of segment AB is 14.
