Answer
the rectangular coordinate is (6.15, 7.88)
Step-by-step explanation
Given the following points
B = (10, 52 degrees)
B = ( r, theta)
Let r = 10 and theta = 52 degrees
Step 1: Find sin 52 and cos 52
Sin 52 = 0.7880
Cos 52 = 0.6157
Step 2: find the x and y - coordinates
X - coordinate = r x cos 52
y - coordiante = r x sin 52
x - coordiante = 10 x 0.6157
x - coordiante = 6.15
y - coordinate = 10 x 0.7880
y - coordinate = 7.88
Therefore, the rectangular coordinate is (6.15, 7.88)
