-1., 1, 2, 2
Step-by-step explanation:
A term is a single mathematical expression. It may be a single number (positive or negative), a single variable ( a letter ), several variables multiplied but never added or subtracted. Some terms contain variables with a number in front of them.
Answer:
Bisect the segment that is the sum of the given segments
Step-by-step explanation:
You want to construct a line segment whose length is the average of two given line segments.
<h3>Solution</h3>
You know that the average of two lengths is half their sum. To construct a line that is half the sum ...
- Construct a segment equal to the sum. For example, from point X on a line, mark XY = AB to the left of X, and XZ = CD to the right of X. Segment YZ will be the sum of AB and CD.
- Bisect it. Draw arcs above and below YZ with the same radius equal to more than half of YZ. The line through the intersection points of each pair of arcs will be the perpendicular bisector of YZ. If it intersects YZ at Q, then YQ = QZ = average of AB and CD.
C = 82.8°
<span>b = 27.5 </span>
<span>Here's the working in case you need to see it. </span>
<span>Using Law of Cosines to first find b: </span>
<span>b² = a² + c² - 2acCOS(B) </span>
<span>b² = (41)² + (20)² - 2(41)(20)COS(36) </span>
<span>b = about 27.5 </span>
<span>Now using Law of Sines to find A </span>
<span>sin(36) / (27.5 = sin(A) / (41) </span>
<span>sin(A) = 41sin36 / 27.5 </span>
<span>sin(A) = 0.876334376145 </span>
<span>A = SinInverse(0.876334376145) </span>
<span>A = about 61.2° </span>
<span>Now using 180-61.2-36 to find B = 82.8° </span>
<span>Have a good day! </span>
