Help please I dont understand this​

Mathematics

s2008m [1.1K]3 years ago

Answer:

x=6

Step-by-step explanation:

The lengths of line segments \overline{AB} and \overline{AC} because of the two segments and two angles marked as equal in the diagram. Because of this, the arcs \widehat{AB} and \widehat{AC} are equal.

Since there are 360 degrees in a circle, we can now set up the following equation:

(10x-23)+(10x-23)+106=180,\\20x-46+106=180,\\20x+60=180,\\20x=120,\\x=\boxed{6}

WITCHER [35]

The sum of all interior angles of a triangle is 180° thus the measure of the exterior angle m∠K is 102° so option (B) is correct.

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

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are 3 sides and three angles in every triangle, some of which may be the same.

Triangle is a very common figure to deal with in our daily life.

It is known that the sum of all three angles inside a triangle will be 180°.

So,   m∠A +  m∠B +  m∠C = 180°

m∠C = 180° - 58° -  44°

m∠C = 78°.

The exterior angle of C = 180- 78 = 102°.

Hence "The sum of all interior angles of a triangle is 180° thus the measure of the exterior angle to m∠K is 102°".

A square is cut in half on the diagonal creating two equal triangles each triangle has an area of 0.72 square units what is the
Katyanochek1 [597]

In a square all 4 sides are equal, so when you cut it along the diagonal to make a triangle, both the base and the height of the triangle would be the same.


The area of a triangle is found by the formula 1/2 x base x height

Since the base and height are the same the formula becomes Area = 1/2 x S^2 ( where S is the length of a side).

The area is given as 0.72 square units.

Now you have 0.72 = 1/2 x S^2

First multiply both sides by 2:

1.44 = S^2

To find S, take the square root of both sides:

S = √1.44

S = 1.2

The side length is 1.2 units.

The exponential decay graph shows the expected depreciation for a new boat, sell g for $3500, over 10 years.
Alisiya [41]
Okay, the exponential function is
g = a^{x}
The start price of it in t=0 is 3,500, as we can see on the graph. Then, the function becomes
g = 3500^{x}
Let's see at t=2, where the price is g=2000:
2000 =  3500^{x}
Take natural logarithm:
ln 2000 = ln  3500^{x}
x*ln 3500 = ln 2000
x = \frac{ln 2000}{ln 3500} = 0.93
So, the difference between t=0 and t=2 is
x_{t=0}  -  x_{t=2}  = 1 - 0.93 = 0.07
And then we get the change of x in one year equal to 0.035.
So, the final equation is
g =  3500^{1-0.035t}
You can insert any t and see that it is correct, for example t=7
