Answer:
D (13,5)
Step-by-step explanation:
X 2 3 4 5
Y 2 5 9 13
So the ordered pairs are (2,2),(3,5), (4,9), (5,13)
and the ordered pairs for the inverse are
(2,2),(5,3), (9,4), (13,5)
from which D (13,5) is found among the options.
We don't know that they skew but if Q and R are the same length then they aren't. But if Q and R are different lengths then they are skew. It would help to post a picture.
y = 5/9x - 37/3
5x - 9y = 8
-9y = -5x + 8
y = 5/9x - 8/9
y = 5/9x + b
-9 = 5/9(6) + b
-9 = 10/3 + b
-37/3 = b
B= 50.35°
C=91.65°
c= 12.77
Given:
A = 38°
b= 10 and a=8.
Required:
angles B and C, and sides c.
By using the rule for law of sines
=> 0.77
B= (0.77) => 50.35°
For angle C:
angle C= 180 - A - B => 180 - 38 - 50.35
=91.65°
For side c:
c= => 8()
