Answer:

15v - 35

Step-by-step explanation:

start by distributing 5 to 3v.

5(3v - 7) aka 5 · 3v ⇒ 15v

distribute 5 to -7.

5(3v - 7) aka 5 · -7 ⇒ -35

you are left with 15v and -35, therefore your simplified expression is 15v - 35.

i hope this helps! have a lovely day <3

Answer:

$15v-35$

Step-by-step explanation:

The distributive property states that $a(b+c)=a*b+a*c$ , where $a$ , $b$ , and $c$ are real numbers. In this case, $a=5$ , $b=3v$ , and $c=-7$ . Therefore, $5(3v-7)=5*3v+5*(-7)=15v-35$ . Hope this helps!

Answer:

Step-by-step explanation:

Using the sine ratio in the right triangle

sin40° = $\frac{opposite}{hypotenuse}$ = $\frac{AC}{AB}$ = $\frac{AC}{7}$

Multiply both sides by 7, thus

AC = 7sin40° → A

Answer:

$opposite\approx 70.02$

Step-by-step explanation:

The triangle in the given problem is a right triangle, as the tower forms a right angle with the ground. This means that one can use the right angle trigonometric ratios to solve this problem. The right angle trigonometric ratios are as follows;

$sin(\theta)=\frac{opposite}{hypotenuse}\\\\cos(\theta)=\frac{adjacent}{hypotenuse}\\\\tan(\theta)=\frac{opposite}{adjacent}$

Please note that the names ( $opposite$ ) and ( $adjacent$ ) are subjective and change depending on the angle one uses in the ratio. However the name ( $hypotenuse$ ) refers to the side opposite the right angle, and thus it doesn't change depending on the reference angle.

In this problem, one is given an angle with the measure of (35) degrees, and the length of the side adjacent to this angle. One is asked to find the length of the side opposite the (35) degree angle. To achieve this, one can use the tangent ( $tan$ ) ratio.
