Answer:

Angle A is 77°

x = 3

AC = 13

Step-by-step explanation:

Angles A, B and C MUST add up to 180°.  If Angle C is 26°, then the sum of A and B and 26° = 180°.  In other words, A+B = 180° - 26° = 154.

Since A and B are equal, A = B = 154°/2 = 77°

Since this triangle is isosceles, sides AC and BC are equal.  Thus,

7x - 8 = 3x + 4, or

4x = 12.  Then x = 3.

Since AC = 7x - 8, and x = 3, AC = 7(3) - 8 = 21 - 8 = 13

Answer:

<h2><u><em>The lengths of the sides of a small cube are = foot. Volume of cube = side x side x side. V = = cubic foot. Number of small cubes that can be packed in the prism = = = = 180 cubes. Hence, 180 cubes can be packed into rectangular prism. Part B: Unit cube volume is 1x1x1 =1 cubic foot. So, 180 cubes will have 180 cubic foot volume.</em></u></h2>

strojnjashka [21]
The solution to the problem is as follows:

kilo -> 1000 
<span>centi -> 100
 </span>

<span>2.4 x 1000 g = 24 x 100 g. </span>

<span>So, on the left we have 2.4 kg, and on the right we have 24 cg

What is the value of x?<br>x=____​
Setler79 [48]
The answer is x = 6

To solve this you would use the pythagorean theorem which is a^2 + b^2 = c^2

In this problem a = x b = 8 and c = 10

You would then square these numbers
x^2 + 64 = 100

Next, you would subtract 64 from both sides.

x^2 = 36

All that’s left is the find the square root, which is x = 6.

So, therefore, you’re answer is x = 6
