Answer:

  39°

Step-by-step explanation:

It is the same measure as the one labeled 6x-9, since these are vertical angles.

  4x +7 = 6x -9

  16 = 2x . . . . . . . . add 9-4x

  8 = x

  4x+7 = 4(8) +7 = 39

The angle is 39°.

Answer:

32

Step-by-step explanation:

First, combine like terms

4x+7=6x-9

     +9     +9

4x+16=-9

     -16   -16

Then divide by four to isolate x

4x=-25

x=-6.25

Plug in X to get the angle measure .

What’s the area and the perimeter and of the triangle?
asambeis [7]

Answer:

Area = 3.3998

Perimeter = 2.9

Step-by-step explanation:

A method for calculating the area of a triangle when you know the lengths of all three sides.

Let a,b,c be the lengths of the sides of a triangle. The area is given by:

Area =  √  p  ( p − a )  ( p − b )  ( p − c )    

where p is half the perimeter, or  

a + b + c / 2

 p = 1.7 + 1.7 + 2.4 / 2 = 5.8 /  2 = 2.9

a = Area = 3.3998

Heron was one of the great mathematicians of antiquity and came up with this formula sometime in the first century BC, although it may have been known earlier. He also extended it to the area of quadrilaterals and higher-order polygons.

Vinvika [58]

Answer:

y = -x -1

Step-by-step explanation:

Use slope = rise/run to find the equation. The y intercept is given to you ( when x is 0, the y value is always the y intercept) so you add a -1.

One of the volunteers whose Sam77 test result was
zhenek [66]

Using it's concept, it is found that there is a 0.041 = 4.1% probability the chosen volunteer does NOT possess Yq77.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

Researching the problem on the interest, it is found that:

  • There were a total of 590 + 25 = 615 positive tests.
  • Of those, 25 did not possess Yq77.

Hence:

p = 25/615 = 0.041.

There is a 0.041 = 4.1% probability the chosen volunteer does NOT possess Yq77.
