So, x+15 + 2x = 90 
Therefore 3x = 90 - 15 = 75 
and so x=25. 

So the smaller angles are x+15 = 40 degrees and 2x=50 degrees. 
So the larger one is 50 degrees.

Sally was walking to Ocean Front Housing Complex, In miles, how far is her distance?

Vanyuwa [196]

Answer:

Sally is 10 miles

The coordinate ofthe deli is (1, -1)

Step-by-step explanation:

✍️Coordinate of Sally = (-3, 2)

Coordinate of Ocean Front = (5, -4)

The distance of Sally to Ocean Front Housing Complex = the distance between point (-3, 2) and (5, -4).

Use the distance formula, $d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$ , to calculate the distance between (-3, 2) and (5, -4):

$d = \sqrt{(5 -(-3))^2 + (-4 - 2)^2}$

$d = \sqrt{(8)^2 + (-6)^2}$

$d = \sqrt{64 + 36}$

$d = \sqrt{100} = 10$

✅The distance of Sally is 10 miles

✍️the coordinate of Deli would be half the distance between Sally and Ocean Front.

Therefore, use the midpoint formula to calculate the coordinate of the midpoint between Sally (-3, 2) and Ocean Front (5, -4).

Midpoint of (-3, 2) and (5, -4).

$M(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2})$

Plug in the values

$M(\frac{-3 + 5}{2}, \frac{2 +(-4)}{2})$

$M(\frac{2}{2}, \frac{-2}{2})$

$M(1, -1)$

✅The coordinate ofthe deli is (1, -1)

Theory - Roots of a product
3.1    A product of several terms equals zero.    When a product of two or more terms equals zero, then at least one of the terms must be zero.    We shall now solve each term = 0 separately    In other words, we are going to solve as many equations as there are terms in the product    Any solution of term = 0 solves product = 0 as well.
Solving a Single Variable Equation:
3.2      Solve  :    -7n = 0    Multiply both sides of the equation by (-1) : 7n = 0

Divide both sides of the equation by 7:
                     n = 0
Solving a Single Variable Equation:
3.3      Solve  :    n-7 = 0    Add 7 to both sides of the equation :                        n = 7

This is what i got! if i’m wrong i’m so sorry
but i tried. have a amazing day☺️☺️
