Answer:
4) (-3 , 2)
Step-by-step explanation:
Answer:
30°
Step-by-step explanation:
The area of a triangle given sides a and b and angle C is:
area = (ab × sin C)/2
Here we are given sides a and c, and we are looking for angle B, so we have
area = ac × sin B
12 cm² = [(8 cm)(6 cm)(sin B)]/2
24 = 48sin B
sin B = 0.5
B = 30°
If 317+x=609, then x is 292.
609-317=292 therefore, x is 292.
