Answer:

Step-by-step explanation:
A right angled triangle is given to us and we would like to find out the value of sin(A) .
From the triangle we can see that the measure of angle BAC is 30° . Therefore ,

On using sin both sides ,

As we know that the value of sin30° = 1/2. So;

Simplify by converting it into decimal ,

<u>Hence</u><u> </u><u>option</u><u> </u><u>B</u><u> </u><u>is</u><u> </u><u>correct</u><u> </u><u>.</u>
And we are done!
Answer:
x =8
The angles are
3x= 24
7x+4 = 60
13x-8 =96
Step-by-step explanation:
The sum of the angles of the triangle is 180
3x+ 7x+4 + 13x-8 =180
Combine like terms
23x -4 = 180
Add 4 to each side
23x -4+4 =180+4
23x =184
Divide by 23
23x/23 = 184/23
x =8
The angles are
3x= 3*8 =24
7x+4 = 7*8+4 = 56+4 = 60
13x-8 = 13*8-8 =104-8=96
Answer:
Recall from Logarithm law Log a - Log b = Log (a/b)
so, Log 2 - Log 4 = Log ( 2/4)
= Log ( 1/2).
Also from the law
Log (a/b) = Log a - Log b
i.e Log (1/2) = Log 1 - Log 2
Recall: Log 1 = 0
which implies : Log 1 - Log 2 = 0 - Log 2
= - Log 2

Answer:
50%
Step-by-step explanation:
40/80 = 0.5. We multiply this decimal fraction by 100% to obtain the desired percentage: 0.5(100%) = 50%
Answer:
X < -9
Step-by-step explanation:
5a +18 < -27
5a < -27 -18
5a < - 45
5a/5 < - 45/5
a < - 9
