Answer:

Supplementary angles add to 180 degrees.

Angles of a triangle add to 180 degrees.

So, the angles of this triangle are 2x, 3x, and 70.

This means we can have the equation: 5x+70=180, and 5x=110, meaning that x=22

Let  me know if this helps!

Answer:

22

Step-by-step explanation:

So first things first we want to find the angle on the bottom right

That angle is supplementary to the one that is equal to 110 meaning that together they will add up to equal 180

180-110=70

We know that the angles of a triangle will add up to equal 180 so we set up an equation

180=70+2x+3x and solve for x

step 1 combine like terms

2x+3x=5x now we have

180=70+5x

step 2 subtract 70 from each side

180-70=110

70-70 cancels out

now we have

110=5x

step 3 divide each side by 5

110/5=22

5/5 cancels

x=22

so we can conclude that x=22

Calculate the gradient of the straight line which joins A(2,-3) and B(6,9)<br>​
Pie

Answer:

Gradient: m = 3

Step-by-step explanation:

m = change in y/change in x

m = \frac{Y2-Y1}{X2-X1}

m = \frac{9-(-3)}{6-(2)}

m = 12/4

m = 3

10. Both x and y vary inversely with each other. When x is 10, y is 6,which of the following is not a possible pair of correspon
elena55 [62]

9514 1404 393

Answer:

  D) 45 and 1.2

Step-by-step explanation:

The "varies inversely" relationship is described by the equation ...

  y = k/x . . . . . . y varies inversely with x (and vice versa)

The value of k can be found from known values of x and y:

  xy = k . . . . . . multiply the above equation by x

  (10)(6) = k = 60 . . . . using the given values

__

To check if a given pair of numbers satisfies ...

  y = 60/x

you can multiply them together to see if the product is 60.

  (A) 12×5 = 60

  (B) 15×4 = 60

  (C) 25×2.4 = 60

  (D) 45×1.2 = 54 . . . . . not a possible pair of corresponding values.

45 and 1.2 are not a possible solution for x and y.

A table is in the shape of a regular pentagon with a side length of 3 feet and an
ehidna [41]

Answer:

15.5 ft²

Step-by-step explanation:

The area (A)  of a regular polygon is calculated as

A = \frac{1}{2} pa ( p is the perimeter and a the apothem )

Here side of regular pentagon is 3 ft, thus

perimeter = 5 × 3 = 15, so

A = 0.5 × 15 × 2.06 ≈ 15.5 ft ( to the nearest tenth )
