ozzi3 years ago
6 0

Answer:

it's answer is 73°

Step-by-step explanation:

< DCB = 50°

< ACB = x

< CAB = 57°

< ABC = < DCB = 50° {Being alternate angles }

Now

x + 50° + 57° = 180° { being sum of angles of triangle }

x + 107° = 180°

x = 180° - 107°

Therefore x = 73°

Hope it will help :)❤

Answer:

4/6

Step-by-step explanation:

The probability of rolling a 6 is 1/6 as shown in the left section.

The sum of -7 times a number and 8 times the sum of the number and 1 is the same as the number minus 7
Vladimir79 [104]

Answer:

8 = -7

This statement is false.

Step-by-step explanation:

The number will be represented by x

-7x + 8(x + 1) = x - 7

8 * x = 8x

8 * 1 = 8

-7x + 8x + 8 = x - 7

Add like terms

-7x + 8x = x

x + 8 = x - 7

-x         -x

8 = -7

This statement is false.
