Answer:

JKL=127°

BEF=63°

m 1=90°

CBY=66°

Step-by-step explanation:

JKL:

the two lines are parallel and cut by one line so the corresponding angles just be the same.

BEF:

(7x-14)=4x+19

add 14 to each side

7x=4x+33

subtract 4x from each side

3x=33

divide each side by 3

x=11

implement that into 4x+19

4(11)+19

44+19

m 1:

Since the congruent angles is 90 and 90 + m 1= 180° the m 1 has to be 90°

3x+9+6x=180 since they are corresponding angles on a parallel line and corresponding angles must equal 180° in total

9x+9=180

subtract 9

9x=171

divide each side by 9

x=19

3(19)+9

66°

Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!

The expression 3(x-9) is equivalent to

11111nata11111 [884]

Answer:

3(x)-3(9)

Step-by-step explanation:

The brackets means you times everything within the brackets with everything outside it. So it would be 3 times x take away 3 times 9
