you add them then subtract by 180 to find the unknown angle
If it's a triangle then: 180-sum of known angles = unknown angle
to find measurement , and angle .
A protractor is one of them
With the protracter, its 180 degrees!!

When your making a homemade balance to find mass, take the mass of a known object, like pennies (2.6 grams) and compare it with the unknown object. When both are equaled to each other, then you know that the unknown object is 2.6 grams or a little more than that.
To find the weight of an unknown object using standard masses and a scale, you can use a balance scale. Place the unknown object on one side and add standard masses to the other side until the balance is achieved. The sum of the standard masses used will be equal to the weight of the unknown object. To find the weight of an unknown object using a ruler, you can use the concept of density. Measure the dimensions of the object to calculate its volume, then weigh the object to find its mass. Using the formula density = mass/volume, you can determine the weight of the object by multiplying its volume by the density of the material it's made of.
The angles are: 150+30 = 180 degrees
