Answer:
190
Step-by-step explanation:
1/2(6+13)(5)
6+ 13 = 19*5 = 95
95/ 1/2= 190
8 days because 4/5 = 8/10 and he is using 1/10 a day.
Answer:
x = 80 degree
Step-by-step explanation:
As sum of all angles in a triangle is equal to 180
so:
According to the given figure:
70 + 30 + x = 180
By simplifying
100 + x = 180
x = 180 - 100
x = 80 degree

For the transformation

the Jacobian is

with determinant

The vertices of the triangle in the
-plane are



Then the integral is
