Ricardo is constructing the inscribed circle for △abc . he has already used his compass and straightedge to complete the part of the construction shown in the figure.

which construction could be his next step?

construct the line through points a and r.

construct the angle bisector of ∠a .

construct the perpendicular to bc through point r.

construct the angle bisector of ∠sbq .

Just took the test and got it correct °˖✧◝( ⁰ ▿ ⁰ )◜✧˖°

Step-by-step explanation:

Look at the image down below :)

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
