I NEED THIS DONE, PLEASE SHOW ALL WORK!! PICTURE 1 IS FOR QUESTION 3 AND PICTURE 2 IS FOR QUESTION 2. THANK YOU

fill in the blanks in the following proof:

1. given: 4x=8(x-2)
prove: x = 4

statement — reason
1. 4x=8(x-2) — 1.
2. — 2. distributive property
3. -4x = -16 — 3.
4. x = 4 — 4.

2. write a paragraph for the following conjecture

given: m < SQR = 55°
m < PQS = 35°
prove: △PQR is a right triangle

3. write a paragraph proof, flowchart, or 2 column proof for the following

given: m < 1 = 27°, < 1 ^ < 2 are supplementary
prove: m < 2 = 153°

Answer:

See explanation

Explanation:

Question 1. Write two-column proof.

Statement Reason

1.
4x=8(x-2) Given

2.
4x=8x-16 Distributive Property of Equality

3.
4x-8x=8x-8x-16\\ \\-4x=-16 Subtraction Property of Equality

4.
x=4 Division Property of Equality

Question 2.

Statement Reason

1.
m\angle SQR = 55^(\circ) Given

2.
m\angle PQS = 35^(\circ) Given

3.
m\angle SQR+m\angle PQS=m\angle PQR Angle Addition Postulate

4.
m\angle PQR=55^(\circ)+35^(\circ)\\ \\m\angle PQR=90^(\circ) Substitution Property of Equality

5.
\angle PQR is a right angle Definition of a right angle

6.
\triangle PQR is a right triangle Definition of a right triangle

Question 3:

Statement Reason

1.
\angle 1 and
\angle 2 are supplementary Given

2.
m\angle 1+m\angle 2=180^(\circ) Definition of supplementary angles

3.
m\angle 1=27^(\circ) Given

4.
27^(\circ)+m\angle 2=180^(\circ) Substitution Property of Equality

5.
27^(\circ)-27^(\circ)+m\angle 2=180^(\circ)-27^(\circ)\\ \\m\angle 2=153^(\circ) Subtraction Property of Equality
