Answer:
One
Step-by-step explanation:
14/sin(54) = 7/sinC
sinC = 0.4045084972
C = 23.86, 156.14
Since 156.14+54 = 210.14 > 180
Only one triangle can be formed with angle 23.86° at C
Answer:
3
Step-by-step explanation:
To find the common ration, we take the 2nd term and divide it by the first term
15/5 = 3
Let check by taking the third term and dividing by the 2nd term
45/15 =3
The common ratio is 3
X^2/9 +7/3
~I believe this is the answer.
Answer:
(4,1)
Step-by-step explanation:
x+y=5
x- y=3
Add the equations together to eliminate y
x+y=5
x- y=3
--------------------
2x = 8
Divide each side by 2
2x/2 = 8/2
x = 4
Now we can find y
x+y = 5
4+y = 5
Subtract 4 from each side
4+y-4 = 5-4
y =1
