Answer:
B = 75°
Step-by-step explanation:
Using the Sine rule:
a / sin A = b / sin B = c / Sin C
a / sin A = b / sin B
20 / sin 48 = 26 / sin B
Cross multiply :
Sin B * 20 = sin 48 * 26
Sin B = (sin 48 * 26) / 20
Sin B = 0.9660882
B = sin^-1(0.9660882)
B = 75.036
B = 75°
C because 6-3=3-1/4=2 3/4 so c
Answer:
C. 5 by 3 by 2
Step-by-step explanation:
The surface area of a rectangular prism is given by:
If the length of the prism is
the width of the prism is
and the height of the prism is:
The surface area becomes:
Multiply within the parenthesis:
Add:
square units.
Hence the correct choice is C.
