Sedbober [7]

Answer:the length of line segment AC is 14

Step-by-step explanation:

The diagram is shown in the attached photo

Since Angle A B C and B C A are congruent. It means that they are equal. An isosceles triangle is a triangle that has two equal sides and two equal base angles. Since Angle A B C and B C A are equal, it means that the triangle is an isosceles triangle. It also means that sides AC and AB are equal. The expression becomes

3x - 7 = 2x

3x - 2x = 7

x =7

To determine the length of line segment AC. We will substitute x = 7 into 3x - 7. It becomes

3×7 - 7 = 21 - 7 = 14

Use a special right triangle to express sin 45 degrees as a fraction

Alekssandra [29.7K]

Answer:

Step-by-step explanation:

in a right angled triangle angles given are 45,90

Then third angle is also 45 °

as two angles are 45° each.

Then sides are also equal.

Let the equal sides be each =x

then hypotenuse=√(x²+x²)=√(2x²)=x√2

sin 45°=x/(x√2)=1/√2
