Answer:
180
Step-by-step explanation:
180 because it is obtuse
A=<4.60,7.20>
b=<5.10,2.70>
The scalar product, or the inner product, or the dot-product, is by summing the products of the respective directions,
a.b=4.6*5.1+7.2*2.7
=23.46+19.44
=42.9
2 Dimensional shape with 5 obtuse angle is <em>Pentagon.</em>
F(x) = 3x - 5
f(2) = 3 (2) - 5
f (2) = 6-5
f (2) = 1
