Answer:

1. 4/5, 3/5, 4/3 || 2. x = 13.78

Step-by-step explanation:

Sin = Opposite/Hypotenuse = 16/20 = 4/5

Cos = Adjacent/Hypotenuse = 12/20 = 3/5

Tan = Opposite/Adjacent = 16/12 = 4/3

So the answer is 4/5, 3/5, 4/3

2) The unknown side is the opposite, and 21 is the hypotenuse. Opposite/Hypotenuse is the sine function.

Sin(41) ≈ 0.656

0.656 = x/21

x = 13.776

The closest answer to this is 13.78

Answer:

x = 18

Step-by-step explanation:

This problem can be solved using concept of Pythagoras theorem.

Pythagoras theorem states that in a right angled triangle, if "a" and "b" are sides containing the right angle and h is hypotenuse then the relation between them is $a^2 + b^2 = h^2$

_________________________________________

Given in the problem

a = 24

b = x

h = x+12

applying Pythagoras theorem

$24^2 + x^2 = (x+12)^2\\=> 576 + x^2 = x^2 + 24x + 144\\=>576 = x^2 + 24x + 144 - x^2\\=> 576 = 24x + 144 \\=> 576 - 144= 24x\\=> 432 = 24x\\=> x = 432/24 = 18$

for (x+12)^2 we have used formula $(a+b)^2 = a^2 + 2ab + b^2$

Thus, value of x is 18.

Alberto rode the train 198 miles

Natali5045456 [20]

Answer: Alberto traveled 792 miles as total distance.

Step-by-step explanation:

Since we have given that

Distance rode by the train = 198 miles

Number of times round tip in last month = 4 times

We need to find the total distance that Alberto traveled.

So, Total distance that Alberto traveled is given by

$198\times 4\\\\=792\ miles$

Hence, Alberto traveled 792 miles as total distance.

A mother had a girl named Mia when she was 18. Four years later, when she was twenty two, she had triplets. Then a year later, a

dexar [7]

She was 22 when she had triplets
so if the triplets are 12 then just add
22+12=34
or when she had Mia she was 18
if Mia is 16 then add
18+16=34
Also, she had another child at 23
if the child is 11 then add
23+11=34
Hope it helps! :)

schepotkina [342]

answer:

21 + 3x (you would not put the x again since it is already given)

step-by-step explanation:

we have to distribute 3 to the expression in the parenthesis

3 (7 + x)

= 21 + 3x

this will be the expression once we distribute
