Answer:

Step-by-step explanation:

LHS = Sin² ∅ + Sin² ∅*tan² ∅

= Sin² ∅ [1 + tan² ∅ ] {Sec² ∅ - tan² ∅ = 1}

= Sin² ∅ *Sec² ∅

= Sin² ∅ * $\frac{1}{Cos^{2} }$

= Sin² ∅ /Cos² ∅

= tan² ∅ = RHS

Scientific notation 9.78 × 10^5 - 732,000 It has to be either 2.46 × 10^5 or 2.46 × 10^3

Morgarella [4.7K]

Answer:

$2.46\times 10^5$

Step-by-step explanation:

$9.78 \times 10^5 - 732,000\\= 9.78 \times 10^5 - 7.32 000\times 10^5\\= 9.78 \times 10^5 - 7.32\times 10^5\\= 2.46\times 10^5$

Find the value of x in a triangle with one side 11 and 1 angle being 28

Andre45 [30]

Answer:

C: 12.5

Step-by-step explanation:

The sides x and 11 could be defined as the Adjacent angle and the Hypotenuse. This means that we will use the cos function to solve this.

First we can set up our equation

$cos28=\frac{11}{x}$

Next we can solve for x by multiplying by x and dividing by $cos 28$

$x=\frac{11}{cos28}\\\\x=12.458\\\\x=12.5$

–6 + (–12) Evaluate the expression

Elanso [62]

Answer:

-18.

Step-by-step explanation:

They're both negative numbers being added to each other, so you'd add 6 and 12 (which is 18) and then put a negative sign before the 18. Therefore, your answer is -18.

I hope this helps, have a nice day.
