Triangle interior angles theorem
answer and explain briefly

x=62

Step-by-step explanation:

(x+1)+ x+55=180

-55               -55 (take away the 55)

(x+1)+ x= 125 (take out of parenthesis)

x+1+ x= 125

2x+ 1= 125  (add the two x's together)

-1         -1        (take away the one)

2x= 124  (divide by 2)

     2

x=62

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70

7000

50=33x+22
