The height would be 12. This is because the area formula for a triangle is base times height divided by 2.
Therefore 12 x 5 = 60 and 60/2 = 30 :)
Obtuse angles are more than 90° and less than 180°
The lines have equal gradients;
m
Equation of line 2;
y=mx+c
y=
x+c
-15=
+c
c=-11
y=4/5x-11
Subtract to find the difference in calories:
150-78 = 72
divide the difference by 150:
72/150 = 0.48
Multiply by 100 to get the percent:
0.48 x 100 = 48%
Answer: 48 %
