Let

a-------> one of the numbers

b------> the other number

we know that

a+b=x ----> equation A

a=12

substitute the value of a in the equation A

12+b=x

solve for b

Subtract 12 from both sides

12+b-12=x-12

b=x-12

therefore

<u>the answer is</u>

The other number is x-12

Solve the unknown angle measure?<br><br>Help Any1 ASAP! Will Mark Brainliest!
zlopas [31]

Answer:

X=40°

X=30°

X=50°

Step-by-step explanation:

Let our unknown angles be denoted by X

Part I

We are given the sum of the angles as 70°, the known as 30° and the unknown as X;

To find X, we subtract the known angle from the sum as:

X=70°-30°=40°

Hence X= 40°

Part II

We are given the sum of the angles as 70°, the known as 40° and the unknown as X;

To find X, we subtract the known angle from the sum as:

X=70°-40°=30°

Hence X= 30°

Part III

We are given the sum of the angles as 80°, the known as 30° and the unknown as X;

To find X, we subtract the known angle from the sum as:

X=80°-30°=50°

Hence X= 50°
