Answer:
NEITHER
Step-by-step explanation:
The sine of 1/2 the angle = 13 / 32
so this angle = 23.9695 degrees
Therefore the required angle = 2 * 23.9695 = 47.939 to 3 DP's.
Answer:
(16, 6 )
Step-by-step explanation:
Basically you are expressing the points (dots ) in coordinate form
Locate x = 16 on the x- axis ( between 14 and 18 )
Then go vertically up to the point at (16, 6 )
11/2 * -11/4 = (11*-11) / 2*4 = -121 / 8
= -15 1/8 answer
-2 1/4 * -4 1/2
= -9/4 * -9/2
= 81/8
= 10 1/8 answer
