The triangles KLH and FLH are congruent by the hypotenuse leg theorem (HL theorem for short) because KL = LF is one pair of congruent legs and LM = LM is the pair of congruent hypotenuses. This theorem only works for right triangles.

By CPCTC (corresponding parts of congruent triangles are congruent), this means we can say that the bottom two angles KHL and FHL are congruent

So,

angle KHL = angle FHL

6y = 4y+18 ... substitution

6y-4y = 4y+18-4y .... subtract 4y from both sides

2y = 18

2y/2 = 18/2 ... divide both sides by 2

y = 9

Answer: 9

Find the value of x for which m parallel to n <br> A. 31 <br> B. 33 <br> C. 39 <br> D. 41
olya-2409 [2.1K]
Hello!

We are told that n and m are parallel.
The angle that measures 105 degrees is supplementary with the alternate interior angle of the angle which measures (3x - 18) degrees. Supplementary angles add to equal 180 degrees, so we can make an equation by first finding the measure of the alternate interior angle.

180 - 105 = 75

The alternate interior angle measures 75 degrees, so we can set that equal to 3x - 18 to solve for x since alternate interior angles are congruent.

75 = 3x - 18
93 = 3x
31 = x

Answer:
x = 31

ahrayia [7]

Answer:

4^{-8} \\4^{-2}\\4^{8}\\4^2

Step-by-step explanation:

For the first few exponents multiply and the rest they add because like terms.

The trick is that when you raise a power to a power you multiply. Otherwise you add if the base value is the same.

suppose your average, after taking 4 quizzes is 70 out of 100. what must your average be on the next 4 quizzes to increase your
exis [7]

Answer:

94

Step-by-step explanation:

Average = Total / Number of Data

70 \times 4 = 280

You have a total of 280 points after 4 quizzes.

4+4=8 quizzes in total

Total you need for average to be 82

82 \times 8 = 656

Number of points you need to hit required:

656 - 280 = 376

You need 376 points in total for the next 4 quizzes.

376  \div 4 = 94

You need an average of 94 points on the next 4 quizzes.
