Answer:

Our total amount value is $4.86.

Step-by-step explanation:

The total amount given is $30.

Now  8 % of $30 = \frac{8}{100}  \times 30 = 2.4

or, 8% of $30  = $2.4

Now adding $30 and $2.4,

$ 30 + $2.4  = $32.4

Finding 15% of the total $32.4,

we get  \frac{15}{100} \times 32.4 = 4.86

or, 15% of $32.4   = $4.86

hence, our total amount value is $4.86.

Each<br>angles<br>of<br>an equilateral<br>traingle is 60, proove it<br>experimentally<br>​
MArishka [77]

Answer:

True

Step-by-step explanation:

We knwo this is true because a triangle angle theorem is that the sum of the angles in a triangle is equal to 180 degrees.

Since tri = 3 then,

=> 180/3 = 60

Equal = same --> def. of equilateral triangle

Thus, we know it is true that in an equilateral triangle, each angle is 60 degrees

Hope this helps!

The question is in the picture please explain.
lapo4ka [179]

Answer:

x = 78

Step-by-step explanation:

Look at Triangle DBH. Two of its angles are known. Let y = <DHB

47 + 31 + y  = 180        All triangles have 180 degrees. Combine the left.

78 + y = 180                Subtract 78 from both sides.

78-78+y = 180-78        Combine

y = 102

Notice that y + x = 180   They form a straight line.

102 + x = 180                   Subtract 102 from both sides.

x = 78

You should notice that x is an exterior angle. (I didn't at first).

Exterior angles are the sum of the two remote interior angles which in this case, are 31 + 47 = 78

Much shorter and much easier.
