Order 2 rectangle has only 2
Answer:
Step-by-step explanation:
take 64 degree as reference angle
using cos rule
cos 64=adjacent/hypotemuse
0.43=QR/10
10*0.43=QR
4.3=QR
Answer:
<em> </em>
Step-by-step explanation:
Since 
is below 
, you would move the decimal right 
times.
That will get you to .
Since we moved it right two times, we get a number in between

Answer:No, the sum of the parallelogram's four angles must be equal to 360
Step-by-step explanation:
All four of a parallelogram's angles must add up to 360. Here, the angles only add up to 45 * 2 + 75 * 2 = 240 degrees.
Also, two adjacent angles must add up to 180. Here, the two adjacent angles 45 and 75 only add up to 120 degrees.
Measuring the Volume of Solids. The volume of solids is expressed in cubic measurements, such as cubic centimeter or cubic meter. Here is an example of a way to measure a solid: Rectangular prism - Multiply the measurement of the length times the width, then times the height.
