how do u know x=60
To solve for x, look at the given image where the two angles are labeled as 3x and 30. Since 3x is the measure of angle C and it is complementary to angle A, the sum of angles A and C should be 90 degrees. Therefore, you can set up the equation 3x + 30 = 90 and solve for x. Substituting in the given values, you get 3x + 30 = 90, which simplifies to 3x = 60, and solving for x gives x = 60.

Sure! Here is a visual aid to help you visualize the problem:
Angle A 60°
/
/
/

Angle B 120°
In this visual aid, angle A is 60 degrees and angle B is 120 degrees and they form a straight line. Angle B is complementary with angle C. So, we need to find angle C.
From the information given:
Angle A + Angle B = 180 degrees (as they form a straight line)
Angle A = 60 degrees
Therefore, to find the measure of angle C:
Angle C + 120 = 180
Angle C = 180 - 120
Angle C = 60 degrees
Let me know if this visual aid helps clarify the solution!

Angle A + Angle B = 180 degrees (as they form a straight line)
Angle A = 60 degrees
Therefore, to find the measure of angle C:
Angle C + 120 = 180
Angle C = 180 - 120
Angle C = 60 degrees

Angle C
In this visual aid, angle A is 60 degrees and angle B is 120 degrees. Angle A and angle B are vertical angles, so they are congruent. Angle B is complementary to angle C, so the sum of angle B and angle C will be 90 degrees.
From the information given:
Angle A = 60°
Angle B = 120°
Angle C = ?
To find the measure of angle C:
Angle B (120°) + Angle C = 90°
120 + Angle C = 90
Angle C = 90 - 120
Angle C = -30 degrees
Therefore, the measure of angle C is -30 degrees. Let me know if this visual aid helps clarify the solution!

In this visual aid, angle A is 60 degrees and angle B is 120 degrees. Angle A and angle B are vertical angles, so they are congruent. Angle B is complementary to angle C, so the sum of angle B and angle C will be 90 degrees.
From the information given:
Angle A = 60°
Angle B = 120°
Angle C = ?
To find the measure of angle C:
Angle B (120°) + Angle C = 90°
120 + Angle C = 90
Angle C = 90 - 120
Angle C = -30 degrees
Therefore, the measure of angle C is -30 degrees. Let me know if this visual aid helps clarify the solution!

Sure! Given the information:
1. Angle A and B are vertical angles, which means they are congruent.
2. Angle B is complementary to angle C, which means the sum of angles B and C is 90 degrees.
3. The measure of angle A is 33 degrees.
We need to find the equation that will allow us to solve for the measure of angle C.
From the information given, we know:
Angle A = 33 degrees
Angle B = 33 degrees (as they are vertical angles)
Angle B + Angle C = 90 degrees
Therefore, the correct equation to solve for the measure of angle C would be:
33 + C = 90
This equation represents the sum of angle B (33 degrees) and angle C equals 90 degrees. Solving this equation will give us the measure of angle C.
I hope this clears up any confusion! Let me know if you need further clarification.

could it be solved by doing 90-33?
Yes, you can definitely solve for the measure of angle C by subtracting the measure of angle A (33 degrees) from 90 degrees.
When you subtract 33 from 90, you get:
90 - 33 = 57
Therefore, the measure of angle C is 57 degrees.
So, in this case, you can solve for the measure of angle C by subtracting the measure of angle A from 90 as well. Thank you for bringing up this alternative method!
