Answer:
z =15cm and
y=9.0cm
Step-by-step explanation:
Use sine rule
12/ sin53 = z / sin 90
Z = 12 x sin 90 / sin 53
Z = 15cm
To find y the angle opposite to y will be 180-(90+53)=37º
So
15/sin 90= y/sin37
y= 15 x sin37 /sin 90
y = 9.0cm
Area of a triangle is base × height ÷2
base=8x+4 x=-4/8 x=-1/2
height=3x-4 x=4/3
A=b×h÷2
A=(-1/2×4/3)÷2
A=(-4/6)÷2
A=(-4/6)÷2/1 to divide by fractions flip the second and multiply
A=-4/6×1/2
A=-4/12
A=-1/3
This point falls on none of your possible answers.
We can first tell that it falls neither positive or negative in terms of x since the x value is 0.
We can also tell the y term is negative. Therefore, it would fall on the negative y-axis.
Or means not both
if people study both then the number of people studying either french or spanish is 7 less than the total number of peple studig french and spanish because thoe 7 are common to both groups
9+14=total=23
23-7=16 people studing either
proabblity=desiredoutcmes/totalpossibe
desired=16
total=30
so 16/30=8/15 is the probablity
