SOH CAH TOA

Basically, Sin. = opposite/hypotenuse
Cos. = adjacent/ hypotenuse
Tan. = opposite/ adjacent
*adjacent = side next to angle __, hypotenuse = side opposite the right angle aka longest side. 

tan. p = opposite/adjacent.
RQ is opposite of angle p, so 35 would be the opposite. PR is adjacent to angle P, so 12 would be the adjacent. Notice how PQ is also adjacent is angle P, but it CANNOT be THE adjacent in the ratio because it is THE hypotenuse.

tan. q = opposite/adjacent
PR is opposite to angle p, so 12 would be the opposite. RQ is adjacent to angle p, so 35 would be the adjacent.

Final answer: tan. p = 35/12, tan. q = 12/35
*fun fact - these ratios are reciprocals

Answers:
Question 1:
second option : tan P = 35 / 12 and tan Q =12 /35
Question 2:
last option: sin A = 12 /13 and cos A = 5 / 13

Explanation:
In a right-angled triangle, special trig functions can be applied.
These functions are as follows:
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent

Now, let's see what we have here

question (1):
Part (a):
θ = P
opposite = 35
adjacent = 12
tan P = opposite / adjacent = 35 / 12
Part (b):
θ = Q
opposite = 12
adjacent = 35
tan Q = opposite / adjacent = 12 /35

question (2):
Part (a):
θ = A
opposite = 12
hypotenuse = 13
sin A = opposite / hypotenuse = 12 /13
Part (b):
θ = A
adjacent = 5
hypotenuse = 13
cos A = adjacent / hypotenuse = 5 / 13

Hope this helps :)

Please help!! ( you use substitution)
Dvinal [7]
All you have to do is substitute one linear equation into the other one.

So, essentially you will have 2 linear equations side by side each other.

8/5x - 1 = -4/3x - 1

-1 = -4/3x - 8/5x - 1

The solution eventually equals 0.

I need help with this A=1/2 bh for b
NemiM [27]

A = 1/2 bh can be written as

A = bh/2.

2A = (bh/2)(2)

2A = bh

Divide both sides by h to find b.

2A/h = b

Done.

The sum of two numbers is a hundred one number is at least 16 more than the other number. What are the numbers? Please help
spin [16.1K]

Answer:

58 and 42.

Step-by-step explanation:

Let the 2 numbers be x and 100-x.

Also let x be the largest number, so

x ≥ 100 - x + 16     ( 'At least 16' means equal to 16 or greater than 16).

Add in x to both sides:

x + x  ≥ 100 + 16

2x ≥ 116

x ≥ 58.

But since the sum of the 2 numbers is 100,  x must be 58 and the other number is 42.
