It would be the second answer.
Answer:
a = 85° , b = 30° , c = 65°
Step-by-step explanation:
∠ a and 85° are alternate angles and are congruent , so
a = 85°
∠ c and 65° are alternate angles and are congruent , so
c = 65°
a, b and c lie on a straight line and sum to 180° , that is
a + b + c = 180°
85° + b + 65° = 180°
150° + b = 180° ( subtract 150° from both sides )
b = 30°

Answer:
14/3
Step-by-step explanation:
32/6 - 2/3
16/3 - 2/3
16-2/3
14/3
Given the integral
first substitute y = 3x and dy = 3 dx :
then rewrite tan(y) = sin(y)/cos(y) and substitute z = cos(y) and dz = -sin(y) dy :
Recall that 1/z is the derivative of ln|z|. Then back-substitute to get the result in terms of x :
