Adding a negative is the same as subtracting
1. Angle: <span>the union of two rays that have a common endpoint.
</span>2. Acute Angle: <span>an angle whose measure is greater than zero and less than 90°
</span>3. Right Angle: <span>an angle whose measure equals 90°.
</span>4. Obtuse Angle: <span>an angle with a measure greater than 90° but less than 180°.
</span>5. Bisector of an Angle: <span>a set of points which divides the angle into two angles of equal measure.
</span>6. Perpendicular Line: lines that intersect to form right angles.
The answer would be 1/2 in fraction form or 0.5 in decimal
Tan 44° = x/140
x = 140 tan 44°
x approx = 140 * 0.9657 = 135.198
Remember, we need to add another 4 feet, so the answer would be 139.198 feet
Answer:
23
Step-by-step explanation:
2a/3 + 13 where a = 15
Step 1. Substitute a for 15
2(15)/3 + 13
Step 2. Multiply
30/3 + 13
Step 3. Divide
10 + 13
Step 4. Add
