Answer:

Step-by-step explanation:

1.Kknow the following information;

Remember, the sum of degrees of angles in a triangle is 180.

So say if a traingle contained;

<1, <2, <3,

Then:

<1 + <2 + <3 = 180

2. State the given, and set up an equation;

In this case, it is given that;

<1 = 115

<2 = 25

Therefore, set up the equation;

115 + 25 + <3 = 180

3. Solve the equation;

115 + 25 + <3 = 180

Simplify,

140 + <3 = 180

Inverse operations,

140 + <3 = 180

-140 -140

<3 = 40

Given the diagram below, find the value of x. Then find AC,

Stels [109]

Answer:

$x=5,\\AC=14$

Step-by-step explanation:

Since one triangle is inscribed in another, the two triangles are similar. As marked in the diagram, the sides of the larger triangle are exactly two times larger than the corresponding sides of the smaller triangle.

Therefore, we have:

$2(x+2)=4x-6,\\2x+4=4x-6,\\10=2x,\\x=\boxed{5}$

Since AC is marked by $4x-6$ :

$AC=4(5)-6,\\AC=20-6,\\AC=\boxed{14}$
