two adjacent angles form a resulting angle with measure 160°. m∠1=3x° and m∠2 = (2x + 10)°. Solve for x. what are the two unknown angles) measurements?

To solve for x, we can use the fact that the sum of the measures of the resulting angle and the adjacent angles is 180°.

The measure of the resulting angle is 160°.

So, we have:

m∠1 + m∠2 + measure of the resulting angle = 180°

Substituting the given values:

3x° + (2x + 10)° + 160° = 180°

Combining like terms:

3x + 2x + 10 + 160 = 180

5x + 170 = 180

Subtracting 170 from both sides:

5x = 10

Dividing both sides by 5:

x = 10/5 = 2

Now we can find the measures of the unknown angles:

m∠1 = 3x° = 3(2)° = 6°

m∠2 = (2x + 10)° = (2(2) + 10)° = 14°
no one said anything about having a sum of 180°
We are told that the two angles sum to 160°
so, that means
3x° + (2x + 10)° = 160°
5x+10 = 160
5x = 160
x = 30
so the two angles are 90° and 70°
Apologies for the misinterpretation. You are correct.

Given that the sum of the two adjacent angles is 160°, we have:

3x° + (2x + 10)° = 160°

Combining like terms:

5x + 10 = 160

Subtracting 10 from both sides:

5x = 150

Dividing both sides by 5:

x = 30

Now we can find the measures of the unknown angles:

m∠1 = 3x° = 3(30)° = 90°

m∠2 = (2x + 10)° = (2(30) + 10)° = 70°

So, the measure of angle 1 is 90° and the measure of angle 2 is 70°.
