Alright so these ratios have many different forms but the way I use to remember the trigonometric ratios is:
SOH
CAH
TOA
This means:
Sine --> Opposite/Hypotenuse
Cosine --> Adjacent/Hypotenuse
Tangent --> Oppositie/Adjacent
With that in mind, number 1:
Would be Sine, or C.
Number 2 would be, Cosine, or E.
And number 3 would be Tangent, or B.
Hope that was helpful.
D.) There are always 180 degrees in triangles. 147 is already shown, so subtract that from 180. That gives you 33.
X:{a, b, c}, because the numbers(or letters in this problem) cannot repeat.
Step-by-step explanation:
The value of x is
x = 118° < being corresponding angles>
Hope it will help :)❤
Step 1: Find the slope
Point 1 = (2, -1)
Point 2 = (-6, -5)
m = (-5 - - 1) / (-6 - 2) = (-5 + 1) / (-6 - 2) = -4 / -8 = 1/2
m = 1/2
Step 2: Find the y-intercept
Slope-Intercept Form: y = mx + b
-m is the slope
-b is the y-intercept
---Plug in whichever point you want as well as the slope and solve for b
Point = (2, -1)
-1 = (1/2)(2) + b
-1 = 1 + b
b = -2
Step 3: Form the equation
Slope-Intercept Form: y = mx + b
m = 1/2
b = -2
y = 1/2x - 2
Hope this helps!! :)
