Step-by-step explanation:
In a triangle ABC. Please find the attachment for figure.


Side BC=a = 10 in
Using sine law of trigonometry,

Substitute the given value into formula.


Cross multiply and we get

in
It is a isosceles triangle. Therefore, b=c=8.72 in
Hence, The other sides of triangles are 8.72 in and 8.72 in
Answer:
(2, 7 )
Step-by-step explanation:
Given the 2 equations
y = 2x + 3 → (1)
y = 3x + 1 → (2)
Substitute y = 3x + 1 into (1)
3x + 1 = 2x + 3 ( subtract 2x from both sides )
x + 1 = 3 ( subtract 1 from both sides )
x = 2
Substitute x = 2 into either of the 2 equations for corresponding value of y
Substituting x = 2 into (1)
y = 2(2) + 3 = 4 + 3 = 7
Solution is (2, 7 )
