Answer:
B= 50.35°
C=91.65°
c= 12.77
Step-by-step explanation:
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(
)
c= 12.77
Answer:
The linear equations which have one solution are C. , D.
and E.
.
Step-by-step explanation:
From Algebra we know that a system of linear equation has a unique solution when the number of variables is equal to the number of equations. Now we proceed to check if each option fulfills this condition:
A. : Number of equations: 1/Number of variables: 2
B. : Number of equations: 1/Number of variables: 2
C. : Number of equations: 1/Number of variables: 1
D. : Number of equations: 1/Number of variables: 1
E. : Number of equations: 1/Number of variables: 1
The linear equations which have one solution are C. , D.
and E.
