∠2 = ∠3 | Given
∠1 + ∠2 = 180 | Supplementary Angles Postule (If two angles are adjacent and ∠3 + ∠4 = 180| linear, they're supplementary)
∠1 + ∠2 = ∠3 + ∠4 | Transitive property
∠1 + ∠3 = ∠3 + ∠4 | Substitution property
∠1 = ∠4 | Subtraction Property
∠2 = ∠3 | Supplementary Congruent Theorem
To leave something in terms of pi means that you don't have to multiply any numbers by pi when solving; you would just add it to the end. This makes the math much easier to do.
V=pi*r^2*h
V=pi*6.5^2*8
V=338pi

Answer:
Option A is correct because sum of m<2 and m<3 are complementary. So m<2+m<3 =90° .
Step-by-step explanation:
Given: <2 and <3 are complementary angles.
Definition of complementary angles says if two angles sum is equal to 90 degrees then they are called complementary angles.
Statement Reason
1.<2 and <3 are complementary 1. Given
2. m<2+m<3 =90° 2. Definition of complementary <s
3. m<1= m<3 3. Given
4. m<1+m<2= 90° 4.Substitution property of =
5. <1 and <2 are complementary 5. Definition of complementary <s.
Option A matches with the given. We can not use addition properties of equality for statement 2 so, other options are incorrect.
So, according to the given options A is correct.

Answer: 31
Step-by-step explanation: divide 558 by 18
1. BC is 1+3=4 (units)
2. AD is 3+5= 8 (units)
3. Draw the altitude CH from point C, as shown in the figure.
4. Then triangle CHD is a right triangle, with hypothenuse CD, and sides HD and CH.
5.
6. AB=CD=4.47 because the trapezoid is isosceles.
7. P= BC+AD+AB+CD=4+8+4.47+4.47=20.9 (units)
