Answer:
x+y =-6 you can write this equation
Let <em>y</em> = √(<em>x</em> - 10), so that <em>y</em>² = <em>x</em> - 10.
Then <em>x</em> = <em>y</em>² + 10 so that √<em>x</em> = ±√(<em>y</em>² + 10).
So we've rewritten the equation as
<em>y</em> = ±√(<em>y</em>² + 10)
In either case, squaring both sides gives
<em>y</em>² = <em>y</em>² + 10
and eliminating <em>y</em>² gives us the false result
0 = 10
so there is no solution.
Answer:
0=8
Step-by-step explanation:
Answer:
Sin A = 15 / 17
Step-by-step explanation:
Given a right angled triangle, we are to obtain the Sin of the angle A ;
Using trigonometry, the sin of the angle A, Sin A is the ratio of the angle opposite A to the hypotenus of the right angle triangle.
Hence. Sin A = opposite / hypotenus
Opposite = 15 ; hypotenus = 17
Sin A = 15 / 17
