To find x we are gonna use the cosine formula.
Cos 0 = adj/hyp
0 represents theta
Cos 0 = adj/hyp
Cos 0 = 25/40
Convert 25/40 to decimal from
25/40 = 0.625
On a scientific calculator press the key “2nd F” or “Shift” then “cos”(which would give cos inverse) then type 0.625 equal.
Cos-1 0 0.625
= 51.31 degrees
x is therefore 51.3 degrees to the nearest tenth
Answer:
200.131234
Step-by-step explanation:
x=3 and y=2 because 6+6 = 12 and 2 times 3 is 6 :)
Answer:
i think it would be C
Step-by-step explanation:
well SSS you would need all 3 sides
AA you would need two angles
SAS you need two sides and one angle
First move the terms to get
6m-m=13+2
Then collect the like terms and calculate the sum, 5m=15
Divide both sides by 5
And you get m=3
