if the measures of the angles of a triangle are in the ratio 1: 2: 3 find the number of degrees in the smallest angle

Answers

Answer 1

Answer:

Smallest angle = 30

Step-by-step explanation:

Ratio = 1 : 2 : 3

Angles are  x ,2x , 3x

Sum of all angles of triangle = 180

x +2x +3x = 180

           6x = 180

            x = 180/6

           x = 30

Find the gradient of the line segment between the points (-2,3) and (-4,-2).
Give your answer in its simplest form.

Answers

Given:

The two points are (-2,3) and (-4,-2).

To find:

The gradient of the line segment between the given points.

Solution:

The gradient is also known as slope.

The slope formula:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

The endpoints of the line segment are (-2,3) and (-4,-2). So, the gradient of the line is

[tex]m=\dfrac{-2-3}{-4-(-2)}[/tex]

[tex]m=\dfrac{-5}{-4+2}[/tex]

[tex]m=\dfrac{-5}{-2}[/tex]

[tex]m=\dfrac{5}{2}[/tex]

Therefore, the gradient of the given line segment is [tex]m=\dfrac{5}{2}[/tex].

Answers

Answer:

b=9 and b=-21

Step-by-step explanation:

first step: move 195 to the other side by adding to get:

b^2+12b=189

now to find the constant you take the b value which is 12 divide that by 2 and square it. then add the product to both sides. 12/2=6, 6^2=36

b^2+12b+36=189+36

next factor b^2+12b+36.

(b+6)^2=225

square root both sides to get:

b+6=15 and b+6=-15

solve by subracting 6 to both sides and you get the 2 final answers.

b=9 and b=-21

PLS HELP ME 12x - 15 = 6 - 3x

Can you pls show me the solving steps and the answer I have to type a paper on how to solve this problem help me plsss (10 points)

Answers

Answer:

x= 21/15

if you need to reduce it would be x=7/5

Step-by-step explanation:

12x-15 =6-3x

add 3x to both sides

15x- 15 = 6

now add 15 to both sides

15x = 21

lastly divide both sides by 15

x= 21/15

if you need to reduce it would be x=7/5

Answer:

x = 7/5 or 1.4

Step-by-step explanation:

12x - 15 = 6 - 3x             Need to move one variable term to the other side to

+3x              + 3x         isolate it on one side

---------------------------

15x - 15 = 6                   need to +15 to isolate the variable term

     +15   +15

-----------------------

15/15x = 21/15 (simplify 21/15 = 7/5)   need to divide by 15 to isolate x

------------------------

x = 7/5 or 1.4

Find the area of a triangle with a base of 10 inches and a height of 5 inches

Answers

Answer:

area = 25 in^2

Step-by-step explanation:

area = 1/2(10)(5) = 25 in^2

Answer:

The height is 4 inches.

For a triangle, we have Area = 1/2 base times height.

With a = area, b = base and h = height,

we have:

A=1/2bh

We are told that A=10 square inches and b=5 inches, so we need to solve (find h ) for:

10=1/2(5)h

We can get rid of the fraction by multiplying by 2 on both sides:

20=5h

Now divide noth sides by 5 (or multiply by 1/5 , to get

20/5=5h/5 so 4=h

The height is 4 inches.

Step-by-step explanation:
