S1. Line m is parallel to line n       {}            R1. Given

S2. ∠1 ≅ ∠2                   {}                            R2. Vertically opposite angles

S3. m∠1 ≅ m∠2                    {}                     R3. Definition of congruency

S4. ∠2 and ∠3 form a linear pear      {}      R4. Definition of a linear pair

S5. ∠2 is supplementary to ∠3 {}      R5. Linear pair angles are supplementary

S6. m∠2 + m∠3 = 180°              {}                Definition of supplementary angles

S7. m∠1 + m∠3 = 180°              {}                 Substitution Property of Equality  

S8. ∠1 is supplementary to ∠3           {}      Definition of supplementary angles

Question 2:

(a) The property of a square that is also a property of a rectangle is that all the interior angles of both a square and a rectangle equal

(b) The property of a square that is not necessarily a property of all rectangles is that the sides of a square are all equal, while only the length of the opposite sides of a rectangle are equal

(c) The property of a rhombi that is also a property of a square is that all the sides of a rhombi are equal

(d) A property of a rhombi that is not necessarily a property of all parallelogram is that the diagonals of a rhombi are perpendicular

(e) A property that applies to all parallelogram is that the opposite sides of all parallelogram are equal

5. Express log2 6 + log2 7 as a single logarithm.
denis-greek [22]
 When making two logarithms one logarithm you keep the base (in this case that would be 2) and multiply the two numbers (in this case 7 times 6 = 42) so the answer is

log(2) 42

Solve the inequality <br><br> 4n-5&lt;-1
kipiarov [429]

Answer:

n<1

Step-by-step explanation:

4n−5<−1

Add 5 to both sides.

4n−5+5<−1+5

4n<4

Divide both sides by 4.

4n/4<4/4

n<1

In △ABC, AB = 13, AC = 20, BC = 21. Find the length of the altitude AD
nika2105 [10]

The length of the altitude AD is 12 units.

<h3>How to find the height of a triangle?</h3>

The height of the triangle can be found as follows:

We have to find an angle using cosine law before  we can find the height.

Therefore,

20² = 13² + 21² - 2 × 21 × 13 cos B

400 = 169 + 441  - 546 cos B

400 - 610 = - 546 cos B

-210 = - 546 cos B

cos B = -210 / -546

cos B = 0.38461538461

B = cos⁻¹ 0.38461538461

B = 67.3810899783

B = 67.38°

Hence,

sin 67.38° = opposite / hypotenuse

sin 67.38° = AD / 13

cross multiply

AD = 13 sin 67.38°

AD = 11.9999882145

AD = 12 units
