Answer:

Step-by-step explanation:

Use the distributive property to get rid of the brackets.

9i + 2*7 + 2*3i Use the multiplication property to simplify the imaginary terms

9i + 2*3i + 2*7 Do the same to the real term

9i + 6i + 14 Use the addition of like terms property

15i + 14 And that's your answer.

You may not like my terminology, but you have to remember that every text teaches this differently.

Triangle FGH is similar to triangle IJK. Find the measure of side KI. Round your

erastovalidia [21]

Answer:

$5.8$

Step-by-step explanation:

Similar shapes also maintain a constant proportion of sides. Therefore, we can set up the following equation:

$\frac{31}{43}=\frac{\text{KI}}{8}$

Solving, we get:

$\text{KI}=\frac{8\cdot 31}{43}\approx \boxed{5.8}$

Plzzz hurry up and help me if A+B=45 prove that (1+tanA)(1+tanB)=2

Solnce55 [7]

Answer:

see explanation

Step-by-step explanation:

If A +B = 45° then tan(A+B) = tan45° = 1

Expanding (1 + tanA)(1 + tanB)

= 1 + tanA + tanB + tanAtanB → (1)

Using the Addition formula for tan(A + B)

tan(A+B) = $\frac{tanA+tanB}{1-tanAtanB}$ = 1 ← from above

Hence

tanA + tanB = 1 - tanAtanB ( add tanAtanB to both sides )

tanA + tanB + tanAtanB = 1 ( add 1 to both sides )

1 + tanA + tanB + tanAtanB = 2

Then from (1)

(1 + tanA)(1 + tanB) = 2 ⇒ proven
