There are 24 sticks in pattern 6. The diagram indicates that one pattern is made up of one box built from four sticks.

<h3>What is the geometric pattern?</h3>

A geometric pattern is a pattern made out of geometric forms that are generally repeated, much like a wallpaper design.

The given figure shows that one pattern consists of one box formed from the 4 sticks.

Pattrern 1 = 1 box  

Pattern 2 = 2 box

Pattern 6 = 6 box

1 box = 4 stick

Pattern 6 = 6 box = 6 ×4 = 24 sticks

Hence,there are 24 sticks in pattern 6.

Answer:

m<1 = 105°

m<2 = 75°

Step-by-step explanation:

Since lines c and d are parallel to each other, therefore:

m<2 = 75° (corresponding angles are congruent)

m<1 + m<2 = 180° (linear angle pair)

Substitute

m<1 + 75° = 180°

Subtract 75 from both sides

m<1 = 180° - 75°

m<1 = 105°
