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:
If the discs were measured to the nearest milimetre, it might be possible, that they are actually 1.64cm wide instead of only 1.64cm as shown.
Therefore the box would fill up much quicker and there will not be enough space.
Step-by-step explanation:
1.6cm * 16 discs = 25.6cm (would fit)
1.64cm * 16 discs = 26.24cm (would not fit)
3. y=112 this takes a lot of process of elimination so ill save you the paragraphs of numbers
second row - k³⁰/k¹⁴ - k¹⁶
third row - 12 ⁴⁵⁻²³ - 12²²
hope this helps
