Answer:

The tangent of -315 is opp/adj = 1/1 = 1

Step-by-step explanation:

The angle -315 is in the 1st quadrant, in which we see a 45-45-90 triangle. Thus, this triangle has 'opposite side' = 1, 'adjacent side' = 1, and hypotenuse √2. The tangent of -315 is thus opp/adj = 1/1 = 1

Can someone please help me with this.

Answer:

Step-by-step explanation:

Given expression is $|8-6 i|$ .

$|8-6 i|$ is a complex expression.

The value of<em> i </em>is –1.

By definition of absolute value, $|a+b i|=\sqrt{a^{2}+b^{2}}$

Now, substitute $|8-6 i|$ in the above formula.

$\Rightarrow|8-6 i|=\sqrt{8^{2}+(-6)^{2}}$ (since <em>i </em>= –1)

$=\sqrt{64+36}$ (since $8^{2}=64$ and $–6^{2}=36$ )

$=\sqrt{100}$ (Square root of 100 is 10)

= 10

Hence, the value of the expression $|8-6 i|$ is 10.
