Find the value of x. (5x +13) (4x+ 2)° (2x -9)

Mathematics
1 answer:
SOVA2 [1]2 years ago
5 0

Answer:

x = 20

Step-by-step explanation:

By exterior angle theorem, we have:

(4x + 2) \degree + (2x  - 9) \degree = (5x + 13) \degree \\  \\(4x + 2 + 2x - 9) \degree  = (5x + 13) \degree\\  \\(6x  - 7) \degree  = (5x + 13) \degree \\  \\ 6x - 7 = 5x + 13 \\  \\ 6x - 5x = 13 + 7 \\  \\ x = 20

saul85 [17]

they are giving you the answer AB=AC, so what that means is that the angles are congruent to each other so if angle AC=15 and angle DC=5 all the angles will be the same.

The area of a circle is 615.44 in2. What is the diameter of the circle? Use 3.14 for π.
Shalnov [3]
615.44 = (3.14)(radius)^2 

<span>radius = square-root of (615.44/3.14) </span>

<span>diameter = radius x 2 </span>

<span>diameter = 28 inches 

3.14

Is 4/5 equal to 5/10?
vfiekz [6]
No, 4/5 does not equal to 5/10.

Because:- When you try to see if it is proportional, it does not equal it.

4/5 ≠ 5/10

Simplify to make sure.

4/5 ≠ 1/2

4/5 is NOT equal to 1/2.

Therefore, our final answer is that 4/5 does not equal 5/10.

A large basin has the shape of a hemisphere with a radius of 25 inches. Calculate the area of rhe circle of water if the basin i
ANTONII [103]

Answer:

100pi in^2, or 314.16 in^2 to nearest hundredth.

Step-by-step explanation:

The areas of the surface of water for  full basin and area for the surface when the depth is 10 inches are in the ratio 25^2 : 10^2 = 6.25 : 1. (because the depth of the water = radius of the water when the basin is full).

The area for a full basin =  pi r^2 = 625pi in^2.

So the area  when depth is 10 inches =  625pi / 6.25 = 100pi in^2.
