Ilia_Sergeevich [38]
The correct answer for the question that is being presented above is this one: "<span>The missing digit is 3."</span>

The missing digit is represented by A  ⇒  $1A2, where A represents a whole number from 0 to 9.

Try substituting any number from 0 to 9 for A (the middle digit or tens place) , then divide by 11 members.

<span>Option 2:  A = 3  ⇒  $1 </span><span>3 </span>2
$ 132 ÷ 11 = $12

The only one-digit that gives a whole number quotient when it takes the place of tens digit in $1 __2  is<span> 3.</span><span>   Because $ 132 ÷ 11 = $ 12. (Option 2)</span>

The missing digit is 3.

What is the measure of angle A in the triangle?
rewona [7]

Answer:

Angle A = 50

Step-by-step explanation:

We know the 3 angles of a triangle add to 180

A + B+C = 180

2x-10 + 70 + x+30 = 180

Combine like terms

3x+90 = 180

Subtract 90 from each side

3x+90-90=180-90

3x = 90

Divide by 3

3x/3 = 90/3

x = 30

We want to find angle A

Angle A = 2x-10

              = 2(30) -10

               = 60-10

                = 50
