Answer:

∠1 = 135°

∠2 = 45°

∠3 = 45°

∠4 = 135°

∠5 = 135°

∠6 = 45°

∠7 = 45°

∠8 = 135°

Step-by-step explanation:

  • The diagram shows two lines that are intersected by a transversal.  (A transversal is a line that passes through two lines in the same plane at two distinct points).

  • When two lines are intersected by a transversal, the angles in matching corners are called Corresponding Angles
    So  ∠1 = ∠5  , ∠2 = ∠6 , ∠3 = ∠7 , ∠4 = ∠8

  • Angles on one side of a straight line always add to 180°

<u>Using the Angles on a Straight Line theorem</u>

Angle 1 and 2 are on a straight line, so

∠2 = 180 - ∠1 = 180 - 135 = 45°

Similarly,

∠3 = 180 - ∠1  = 180 - 135 = 45°

∠4 = 180 - ∠3 = 180 - 45 = 135°

<u>Using the Corresponding Angles theorem</u>

As ∠1 = ∠5, then ∠5 = 135°

As ∠2 = ∠6, then ∠6 = 45°

As ∠3 = ∠7, then ∠7 = 45°

As ∠4 = ∠8, then ∠8 = 135°

Answer:

∠1=135°

∠2=45°

∠3=45°

∠4=135°

∠5=135°

∠6=45°

∠7=45°

∠8=135°

Step-by-step explanation:

→∠1=∠4[Being vertically opposite angles]

→∠4=135°

→∠1=∠5[Corresponding angles]

→∠5=135°

→∠5=∠8[Being vertically opposite angles]

→∠8=135°

→∠1+∠2=180°[Sum of linear pair]

→∠2=180°-135°

→∠2=45°

→∠2=∠3[Being vertically opposite angles]

→∠3=45°

→∠3=∠6[Alternate angles]

→∠6=45°

→∠6=∠7[Being vertically opposite angles]

→∠7=45°

Solve the equations.<br> a. (x − 2)^2 = 9<br> b. 3(x − 2)^2 = 9<br> c. 6 = 24(x + 1)^2
seropon [69]

Answer: a) x = 5 or -1 b) x = √3+2

c) x = -1/2 or -3/2

Step-by-step explanation:

a) (x − 2)² = 9

First step is to take the square root of both sides to eliminate the square

√ (x − 2)² = √9

x-2 = +-3

x = +3+2

x = 5 and;

x = -3+2

x = -1

x = 5 or -1

b) 3(x-2)² = 9

First we divide both sides by 3 to get;

(x-2)² = 9/3

(x-2)² = 3

Second step is to take the square root of both sides to eliminate the square

√(x-2)² = √3

x-2 = √3

x = √3+2

c) 6 = 24(x+1)²

Dividing both sides by 24, we have

6/24 = (x+1)²

1/4 = (x+1)²

Taking the square root of both sides we have

√1/4 = √(x+1)²

= +-1/2 = x+1

x = +1/2-1 = -1/2 and;

x = -1/2-1 = -3/2

x = -1/2 or -3/2
