a. Parameterize
by

with
.
b/c. The line integral of
over
is




d. Notice that we can write the line integral as

By Green's theorem, the line integral is equivalent to

where
is the triangle bounded by
, and this integral is simply twice the area of
.
is a right triangle with legs 2 and 5, so its area is 5 and the integral's value is 10.
Multiply is product. Divide is quotient
The interior angles are 3, 4, and 6. Angle 3 is adjacent to angle 1, so is not remote.
The remote interior angles to angle 1 are
... A. angle 4
... E. angle 6
Answer:

Step-by-step explanation:
To the find the equivalent of
, evaluate the expression. Start by opening the bracket.

The equivalent of
is 
<span>Since it is given that AB ≅ AC, it must also be true that AB = AC. Assume ∠B and ∠C are not congruent. Then the measure of one angle is greater than the other. If m∠B > m∠C, then AC > AB because of the triangle parts relationship theorem. For the same reason, if m∠B < m∠C, then AC < AB. This is a contradiction to what is given. Therefore, it can be concluded that
Answer: Angle (B) is Congruent to Angle (C)
