Mathematics

They both are complementary, so their sum would be 90 degrees.
5x-12 + 4x+3 =90
9x - 9 = 90
9x = 99
x = 11

So, angle 1 = 5x-12 = 5(11)-12 = 55-12 = 43
angle 2 = 4x+3 = 4(11)+3 = 44+3 = 47

So, your final answers are: angle 1 = 43 degrees & angle 2 = 47 degrees

Hope this helps!

1) What is 15\50 in lowest terms

15/50 simplified would be 3/10 (divided by 5 on each side)
5/9 x 3/10 would be 15/90 or 1/6
1/4 divided by 3/5 would be 5/12, because when you divide fractions you flip the second fraction Ex: 1/4 divided by 3/5 would be 1/4 x 5/3
The prime factorization of 120 would be 2 x 2 x 2 x 3 x 5 or 2^3 x 3 x 5

What is -2 1/4x+3 7/12x-4 2/3 simplified
lesya [120]

Answer:

  (4x -14)/3

Step-by-step explanation:

Assuming you intend mixed number coefficients, only the coefficients of x can be combined.

  (-2 1/4)x +(3 7/12)x -(4 2/3) = x(-2 1/4 +3 7/12) -(4 2/3)

The mixed numbers are added in the usual way.

  (-2 1/4) +(3 7/12) = (-2 +3) +(-1/4 +7/12) = 1 +(-3/12 +7/12) = 1 4/12 = 1 1/3

So the expression simplifies to ...

  (1 1/3)x -(4 2/3)

This might be better written as ...

  (4x -14)/3

<em>Comment on mixed numbers</em>

It is hard to write mixed numbers so they can be properly interpreted in an algebraic expression. In general, they are better written as improper fractions or as decimal numbers (if the decimal terminates).

Paul [167]

From the given condition m ∠LOM = m ∠JKI, m ∠MON = m ∠IKH it is proved that m ∠LON = m ∠HKJ as they are congruent angles.

<h3>What are congruent angles?</h3>

Congruent angles are defined as angles with equal measure. According to the question,

m ∠LOM = m ∠JKI  (given congruent angles)   _____(1)

m ∠MON = m ∠IKH  (given congruent angles)  _______(2)

Add both the side angle  m ∠MON in (1) we get m ∠LOM + m ∠MON = m ∠JKI + m ∠MON

Replace angle  m ∠MON = m ∠IKH from (2)  on right-hand side we get,

m ∠LOM + m ∠MON = m ∠JKI + m ∠IKH  ____(3)

m ∠LOM + m ∠MON = m ∠LON  ( M is the interior point of ∠LON)  ___(4)

m ∠JKI + m ∠IKH = m ∠HKJ  ( I is the interior point of ∠HKJ)  ___(5)

Form (3), (4), and (5) we get, m ∠LON = m ∠HKJ  (Congruent angles)

Hence, from the given condition it is proved that m ∠LON = m ∠HKJ, are congruent angles.
