Refer to the attached image. Since one vertex is the origin and the other two lay on the coordinate axes, the triangle is a right triangle. This means that, if we consider AB to the be base, AC is his height, and vice versa.
Anyway, it means that the area is given by

Since AB is a horizontal segment and AC is a vertical segment, their length is given by the absolute difference of the non-constant coordinate: points A and B share the same x coordinate, so we subtract the y coordinates:

The opposite goes for AC: points A and C share the same y coordinate, so we subtract the x coordinates:

So, the area is

Answer:
y = 5.6
Step-by-step explanation:
Use Sine
Sine = 
Sine 45 = 
Sine of 18 is 0.309
0.309 = 
Multiply 18 on both sides
0.309 x 18 =
x 18
5.562 = y
Round to the nearest tenth:
5.562 = 5.6
Answer:
m<5= 46 degrees
m<8= 134 degrees
Step-by-step explanation:
m<5: all you need to do is subtract 134 from 180
m<8: m<2 and m<8 have the same angle
Multiply 4 * 5, which equals 20, and add the two zeroes(from 40 and 50) on the end.
That gives us:
2000
Answer:
20 outcomes
Step-by-step explanation:
the outcomes of the first times the outcomes of the second
= 4×5
= 20
