Which transformations map the strip pattern onto itself?
hahahah
a horizontal translation and a 180° rotation only
a horizontal translation and a glide reflection
a horizontal translation, a reflection across a vertical line, and a 180° rotation
a horizontal translation only

the correct answer is $7.38

step-by-step explanation:

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.

answer: 486in^2
