Yes it is possible because the acute angle is less then 90 degrees meaning its inside the angle

Answer:

$\boxed{GJ = 76 \ degrees}$

Step-by-step explanation:

According to Angles of intersecting chords theorem:

∠GAJ = $\frac{1}{2} (BD+GJ)$

Where ∠GAJ = 50 , BD = 24 and GJ = ?

50 = $\frac{1}{2} (24+GJ)$

Multiplying both sides by 2

100 = 24 + GJ

GJ = 100-24

GJ = 76 degrees

Solve the following system of equations:

Vladimir79 [104]

Answer:

(-1,1)

Step-by-step explanation:

We can solve this by either graphing and finding ther point the lines intersect, or mathematically, I'll do both.

Graphing:

Mathematically:

−2x + 4y = 6

y = 2x + 3

See the attached graph. The lines intersect at (-1,1)

--------------------

I'll rearrange the first equation (to make it easier for me):

−2x + 4y = 6

4y = 2x + 6

y = (1/2)x + 1.5

Now lets substitute the second equation into the first so that we can eliminate y:

y = 2x + 3

[(1/2)x + 1.5] = 2x + 3

- (3/2)x = (3/2)

x = -1

If x = -1:

y = 2(-1) + 3

y = 1

The solution is x = -1 and y = 1, or (-1,1)

=================

Both approaches give us (-1,1), the solution to the system of equations. It is the only point that satisfies both equations.

Let F be a field, and suppose a EF, a *0. Prove that a has a unique multiplicative inverse.

bezimeni [28]

Answer with Step-by-step explanation:

Let F be a field .Suppose $a\in F$ and $a\neq 0$

We have to prove that a has unique multiplicative inverse.

Suppose a has two inverses b and c

Then, $ac=1,ab=1$ where 1 =Multiplicative identity

$ac=ab$

$c=b$ (cancel a on both sides)

Hence, a has unique multiplicative inverse.
