Two position vectors each start at the origin. The ﬁrst has a magnitude of 35.0 cm, and is at an angle of 15.00 as measured counterclockwise from the

+x—axis. The second has a magnitude of 23.0 cm and an angle of 63.0quot;, also counterclockwise from the +x-axis. (a) What is the area of the parallelogram (in cmz) that has the two vectors as two of its sides? CI’I’I2 What is the length of the longer diagonal of this parallelogram (in cm)?
