Mathematics

Whitepunk [10]2 years ago

Answer:

x = 25

Step-by-step explanation:

Looking at the triangle we know that it is a right triangleor a 90⁰ triangle.

(2x + 15)⁰ + x⁰ = 90⁰

2x + 15⁰ + x⁰ = 90⁰

<u>2x + x</u> + 15⁰ = 90⁰

3x + 15⁰ = 90⁰

3x <u>+ 15⁰ - 15⁰</u> = <u>90⁰ - 15⁰</u>

3x = 75⁰

<u>3x / 3</u> = <u>75⁰ / 3</u>

x = 25⁰

Now plug the x value in the missing angles.

2x + 15⁰

<u>2(25⁰)</u> + 15⁰

<u>50</u><u>⁰</u><u> </u><u>+</u><u> </u><u>15</u><u>⁰</u>

65⁰

According to the sum of triangle, all angles add up to 180⁰. Even though this is a right triangle, it should add up 180⁰ in order to be a triangle.

65⁰ + 25⁰ + 90⁰ = 180⁰

Hope this helps and stay safe, happy, and healthy, thank you :) !!

2 - Population of generalization will include people who will have similar excersing routines and habits if method II is used since sample is choosen from a specific population

Step-by-step explanation:

Past excercising habits may affect the change in intensity to a targeted excersise in different manner. So in method I a greater diversity is included and result of excersing with or without a trainer will account for greater number of variables than method II.

Find the slope of the line through the points (6,16) and (−6,4)
MakcuM [25]

m = \frac{y2-y1}{x2-x1}

m = \frac{4-16}{-6-6} \\m = \frac{-12}{-12} \\\\m = 1

Therefore, the slope of the line is 1. In case if you want to know the equation.

y=mx+b\\y=x+b\\4=-6+b\\4+6=b\\10=b\\

Therefore, the equation is y=x+10 by substituting the (-6,4) or we can substitute (6,16) too.

y=mx+b\\y=x+b\\16=6+b\\16-6=b\\10=b\\

It's the same, you can use any orders given.

Overall, the slope is 1 and the equation is y=x+10
