Answer: 35.54 degrees</h3>
How I got this answer:
tan(angle) = opposite/adjacent
tan(A) = BC/AC
tan(A) = 5/7
A = arctan(5/7) .... apply the inverse tangent, same as arctangent
A = 35.5376778 ... make sure your calculator is in degree mode
A = 35.54 .... rounding to two decimal places
Answer:
B.11.4
Step-by-step explanation:
The sum the 3 angles of a triangle add to 180 degrees
5x+8x+2x+9 = 180
15x+9 =180
Subtract 9 from each side
15x+9-9 =180-9
15x = 171
Divide by 15
15x/15 =171/15
x =11.4
I think this is the answer .
Answer 3 ten of numbers between -5/6,5/8
multiply there denominators by any number ...
-5/6×48= -40/48
5/8×48= 30/48
Hence
30/48,31/48,32/48,33/48,34/48,35/48,36/48,37/48,38/48,39/38.
Answer 4
1. x-5=9
X=9+5=14
2. 7= y+2
7-2=y
5=y
Answer 5 X/9=-2
X= -2×9
X= -18
5t= 30
t=30/5
t=6
hope it helps friend
