work out the missing angles for these irregular polygons #3a, b,c and work out the miss angles for the regular polygon 4a

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour

- (2, -7)

- lines r and s and lines t and u must be parallel

t

step-by-step explanation:

ever thing time 1 is a multiply by 1 it get  

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.
