### Subject: Geometry

If a triangle has two interior angles measuring 34 degrees and 48 degrees, what is the measure of the third interior angle? Classify the triangle as acute, right, or obtuse.

The angles of a triangle add up to 180 degrees, so the third angle would be 98 degrees. Because 98 is greater than 90, the triangle is an obtuse triangle.

### Subject: Pre-Algebra

x + 4 = 8 Solve for x and list the property used.

x = 4 Addition property of equality.

### Subject: Algebra

5(x+4) - 3(x-2) = 24 Solve for x.

1. FOIL using distributive property. 5x + 20 - 3x + 6 = 24 2. Combine like terms. 2x + 26 = 24 3. Use addition property of equality. 2x = -2 4. Use multiplication property of equality. x = -1
