Help please

Levart [38]

Answer:

-0.8 (A) -2.25 (B) -2 (C) (Look at explanation to see answers for first bubbles.)

Step-by-step explanation:

1.4 - 2.2 = -0.8

-0.75 - 1.5 = -2.25

-0.2 - 1.8 = -2

Can anyone check this after me ? did i do it right

____ [38]

Answer:

Yes, it is right. 

Using pythagoras theorum, we found the side to be 10. 

So, the perimeter is 4 times 10, i.e., 40

1. ABCD is a parallelogram. Find the value of x.

Deffense [45]

Answer:

Step-by-step explanation:

1. Since, it is given that ABCD is a parallelogram, therefore opposite angles of parallelogram are equal, hence

∠B=∠D

⇒7x-31=5x+13

⇒2x=44

⇒x=22

Hence, option B is correct.

2. Since, we get x=22, therefore

∠B=7x-31=7(22)-31=154-31=123°

∠B=123°

and ∠D=5x+13=5(22)+13=123°

∠D=123°

Also, ∠A+∠D=180°(corresponding angles)

⇒∠A=180-123

⇒∠A=57°

Now, ∠A=∠C=57°(opposite angles of parallelogram)

thus, Two of the angles measure 57°, and the other two measure 123°.

Therefore, option A is correct.

Bezzdna [24]

Step-by-step explanation:

here

-11r ≥ 220

-11r/-11 ≥ 220/-11 (dividing both side with -11 to eliminate -11 )
