Answer:
B- -2/3 is to the right of -0. 6.
Answer:
6.79
Step-by-step explanation:
First of all, you will have to know how much is 3% of 7 in order to decrease it by that amount.
7 x 0.03 = 0.21
Now that you know the amount, you can subtract it from seven and therefore you have decreased 7 by 3%.
7 - 0.21 = 6.79
Answer:
From figure A
The value of ∠ B = 75.74° , ∠ C = 70.26° and AB = 27.37
From figure B
The value of ∠ A = 42.8° , ∠ B = 106.2° and AC = 30.04
Step-by-step explanation:
<u>Given first figure as :</u>
AC = 28.2
BC = 16.5
∠ A = 34°
Let AB = c
<u>From law of sines</u>
=
=
Or,
=
or,
=
Or, 29.506 =
Or, Sin B =
Or, Sin B = 0.955
∴ ∠B =
0.955
I.e∠ B = 75.74
Now, ∠ C = 180° - ( ∠A + ∠B )
Or, ∠ C = 180° - ( 34° + 75.74° )
Or, ∠ C = 70.26°
Now, Again
=
so,
=
Or,
=
Or, c = 29.09 × 0.9412
∴ c = 27.37
I.e AB = 27.37
Hence, The value of ∠ B = 75.74° , ∠ C = 70.26° and AB = 27.37
<u>From figure second</u>
Given as :
AB = c= 12
BC = a = 16
∠ C = 31°
let AC = b
<u>From law of sines</u>
=
=
Or,
=
or,
=
or,
=
Or,
= 23.52
∴ Sin A =
I.e Sin A = 0.68
Or, ∠ A =
0.68
or, ∠ A = 42.8°
Now, ∠ B = 180° - ( 31° + 42.8° )
Or, ∠ B = 106.2°
Now,
=
or,
=
Or,
=
or, b = 31.3×0.96
∴ b = 30.04
Hence The value of ∠ A = 42.8° , ∠ B = 106.2° and AC = 30.04
