The measure of a triangle is 180 degrees. In other words the sum of the angles of a triangle is 180 degrees

To solve for x set all of the expressions of angles equal to 180 and isolate x

11x - 3 + 7x + 5 + 13x - 8 = 180

31x + (- 6 + 6) = 180 + 6

31x/31 = 186 / 31

x = 6

To find the measure of each angle plug 6 into the x into each individual expression

Hope this helped!

Answer:

-9

Step-by-step explanation:

Plug in -3 for the x value to get 6 + 5 (-3). Multiply 5 by -3 to get -15 and subtract that number from 6 to get -9 as your final answer.

Adam’s father is 3 times as old as Adam. Two years ago, Adam was 15 years old. How old will his father be in 5 years?

Nata [24]

Answer: 56 years

Step-by-step explanation:

Let Adam's age be $x$ , since the father is 3 times as old as him , then the father will be $3x$ .

Two years ago

Adam = $x - 2$

Father = $3x - 2$

since Adam was 15 years old 2 years ago , this means that

$x-2=15$

add 2 to both sides

$x = 17$

Therefore , Adam is presently 17 years old , then the father will be 3(17) years , which means that the father is presently 51 years old.

In 5 years time , the father will be 51 + 5 years old. That is , the father will be 56 years old in 5 years time

Find the area of the regular hexagon

earnstyle [38]

Answer:

Area = 166cm² (Approximately)

Step-by-step explanation:

To solve this, let's recall the formula for the area of a REGULAR Hexagon.

The area of a REGULAR Hexagon is expressed as:

A = (3√3 * a²) / 2

Where a is the length of one side of the Hexagon.

a= 8cm.

Area = (3√3 * 8²) / 2

Area = (3√3 * 64) / 2

Area = (192√3) / 2

Area = 332.55 / 2

Area = 166.28cm²

Area = 166cm² (Approximately)

Select the correct answer from the drop-down menu. Find the product. The product of 2/5a2x and -1/5x2a is

valentinak56 [21]

Answer: $-\frac{2}{25}a^{3}x^{3}$

Step-by-step explanation:

1. The problem asked for the product of $\frac{2}{5}a^{2}x$ and $-\frac{1}{5}x^{2}a$ , therefore, you must mutliply them, as you can see below:

2. According the exponents propertiess, when you have a multiplication of two powers that has the equal base, you must add the exponents. THerefore, you have the following result:

$(\frac{2}{5}a^{2}x)(-\frac{1}{5}x^{2}a)=-\frac{2}{25}a^{3}x^{3}$
