Answer: I think around 0.70
Step-by-step explanation:
Hello,
1)
sin x=3/5==>x=126.869897...° (since in quadrant II)
2)==>cos x<0
cos x=-√(1-sin ² x)=-√(1-9/25)=-4/5
tan x=(3/5)/(-4/5)=-3/4
cotg x=-4/3 =1/tan x
sec x=1/cos x=-5/4
cosec x=1/sin x=5/3
Answer:
2. 180-115 = <u><em>65</em></u>
3. angle = 90-37 = <em><u>53</u></em>
4. angle = 90 - 15 = <em><u>75</u></em>
5. angle = 90-43 = <em><u>47</u></em>
6. 109+71 = 180 = S
7. 19+71 = 90 = C
8. 89+1 = 90 = C
9. 34+56 = 90 = C
10. 75+75 = 150 = N
11. 16+74 = 90 = C
12. 90+90 = 180 = S
13. 65+115 = 180 = S
Hope this helps
