Answer:

see explanation

Step-by-step explanation:

(11)

cos L = \frac{adjacent}{hypotenuse} = \frac{LN}{LM} = \frac{8}{17}

(12)

tan M = \frac{opposite}{adjacent} = \frac{LN}{MN} = \frac{8}{15}

(13)

sin M = \frac{opposite}{hypotenuse} = \frac{LN}{LM} = \frac{8}{17}

The Three angles of a triangle have measures 7x+6,10x-8 and 5x+3.What is the measure of the smallest angle?
g100num [7]

Answer:

43 15/22 degrees

Step-by-step explanation:

The three angles add to 180 degrees

7x+6 +10x-8 + 5x+3 = 180

Combine like terms

22x +1 = 180

Subtract 1 from each side

22x +1-1 =180-1

22x = 179

Divide each side by 22

22x/22 = 179 /22

x =179/22


The smallest angle is

5x+3

5(179/22) +3

895/22 +3

40 15/22 +3

43 15/22 degrees

Fill in the missing statement and reason in the proof of the Alternate Exterior Angles
gulaghasi [49]

The addition property of equality states that if you add the same value to both sides of an equation, the sides of the equation stay equal

∠EGB  and ∠AGF are congruent by <u>addition property</u>

Reason:

AB is parallel to CD;    Given

Points E, G, H, and F are collinear;    Given

The measure of ∠EGF = 180° by angles on a straight line

∠AGF and ∠AGE are adjacent angles, therefore, ∠AGF + ∠AGE = ∠EGF

  • ∴ ∠AGF + ∠AGE = 180° by transitive property

∠CHE and ∠AGF are same side interior angles

  • ∴ ∠CHE + ∠AGF = 180°

∠AGF + ∠AGE = ∠CHE + ∠AGF

Therefore, the measure of ∠AGE is equal to the measure of ∠CHE by <u>addition property of </u><u>equality</u>

  • ∠EGB + ∠AGE = ∠AGF + ∠AGE by linear pair angles

Therefore;

∠EGB  and ∠AGF are congruent by the<u> addition property</u> of equality

A2-b2 ÷5a-5b factorise​
katrin2010 [14]

Answer:

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "b2"   was replaced by   "b^2".  1 more similar replacement(s).

STEP

1

:

           5a + 5b

Simplify   ———————

           a2 - b2

STEP

2

:

Pulling out like terms

2.1     Pull out like factors :

  5a + 5b  =   5 • (a + b)  

Trying to factor as a Difference of Squares:

2.2      Factoring:  a2 - b2  

Theory : A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =

        A2 - AB + BA - B2 =

        A2 - AB + AB - B2 =

        A2 - B2

Note :  AB = BA is the commutative property of multiplication.

Note :  - AB + AB equals zero and is therefore eliminated from the expression.

Check :  a2  is the square of  a1  

Check :  b2  is the square of  b1  

Factorization is :       (a + b)  •  (a - b)  

Canceling Out :

2.3    Cancel out  (a + b)  which appears on both sides of the fraction line.

Final result :

   5 / a -b
