Y= 7x + 20
It’s right trust me
Add the frequency’s together:
84 + 36 + 72 + 84 + 204 = 480
Divide each frequency by the total then multiply by 360 degrees:
A = 84/480 x 360 = 63 degrees
B = 36/480 x 360 = 27 degrees
C = 72/480 x 360 = 54 degrees
D = 84/480 x 360 = 63 degrees
E = 204/480 x 360 = 153 degrees
Answer:
x = 4
Step-by-step explanation:
First, you subtract 1 from both sides, giving you 3x = x + 8
Then you subtract 1x from both sides, so 2x = 8
Divide the 2 from both sides which leaves you with the answer, x = 4
Answer:
another way to write this is 1:3
Cosine = adjacent / hypotenuse so that is the trig ration we use here:-
cos M = 32/41 = 0.78049
m < M = 38.69 degrees to nearest hundredth
