Answer:
68.20°
Step-by-step explanation:
Using Pythagoras rule :
Tanθ = opposite / adjacent
Adjacent = 8ft
Opposite = 20
Tanθ = 20 / 8
θ = tan^-1(20/8)
= 68.198590
Hence, angle of elevation = 68.2°
Answer:
I'm pretty sure the answer is 75%.
Step-by-step explanation:
Well, when you do 60 / 20, you get <u>3.</u>
So, then when you make 3 a percentage,
it comes out 75%.
Hope this is right...!
Answer:
7/3 or 13/15
Step-by-step explanation:
So you told me that it will be
8/(20/9) -2 11/15 I put parenthesis to make it easier to understand for me
so you must know that a/(b/c)=ac/b si
72/20 -2 11/15 so we work with -2 11/15 which is equal to -30/15 + 11/15 and that will be -19/15 so we have
72/20 - 19/15 we simplify
18/5 - 19/15 so we multiply and divide by 3 in 18/5
54/15 - 19/15 and we add up
35/15 which is equal to
7/3
If this is wrong <u>so we work with -2 11/15 which is equal to -30/15 + 11/15 </u> well it should be so we work with -2 11/15 which is equal to -30/15 - 11/15 and that equals -41/15 and we get
54/15-41/15
13/15
