<h3>Answer: SAS</h3>

=================================

How to get this answer:

We're told that AD = BC, so that is one pair of sides that are congruent. This forms the first "S" in "SAS"

The "A" refers to the congruent angles, which happen to be angle DAB and angle CBA, both are 90 degrees

The second "S" in "SAS" is the second pair of congruent sides. Those two sides are the overlapping shared side of AB. It might help to peel the two triangles apart to get a better look.

Note how the angles are between the two pairs of sides mentioned.

Factor completely 4x2 − 8x − 60. (4x − 20)(x + 3) 4(x − 5)(x + 3) (4x − 4)(x + 15) 4(x − 1)(x + 15)

katovenus [111]

after complete factorization of $4x^2-8x-60$ the answer is $4(x+3)(x-5)$

Step-by-step explanation:

We need to factor $4x^2-8x-60$

Taking 4 common and factorizing:

$=4(x^2-2x-15)\\=4(x^2+3x-5x-15)\\=4(x(x+3)-5(x+3))\\=4(x+3)(x-5)$

So, after complete factorization of $4x^2-8x-60$ the answer is $4(x+3)(x-5)$

F(1)=6;f(n)=f(n−1)−2

ch4aika [34]

Answer: f(7) = f(4) + 3(3) = 15 + 9 = 24

Step by Step Explanation:

f(1) = 6

f(n) = f(n-1) + 3

f(2) = f(1) + 3 = 6+3 = 9

f(3) = f(2) + 3 = 12

f(4) = f(3) + 3 = 15

Each term is 3 more than the previous one

Therefore to get from the 4th term to the 7th term you will add 3

For a total of 3 more times.

f(7) = f(4) + 3(3) = 15 + 9 = 24

Hope this helps

What is the length of the side labeled x?

Scorpion4ik [409]

Answer:

AB = 42.15 units

Step-by-step explanation:

In triangle ABD,

By applying Cosine rule in this triangle,

cos(30)°= $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

$\frac{\sqrt{3} }{2}$ = $\frac{AD}{AB}$

$\frac{\sqrt{3}}{2}=\frac{AD}{47}$

AD = $\frac{47\sqrt{3}}{2}$

By applying tangent rule in ΔACD,

tan(44)° = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

tan(44)° = $\frac{AD}{x}$

0.9657 = $\frac{\frac{47\sqrt{3}}{2}}{x}$

0.9657 = $\frac{47\sqrt{3}}{2x}$

x = $\frac{47\sqrt{3}}{2(0.9657)}$

x = 42.15

≈ 42.2 units
