Which equation represents the area of the triangle? A) A = 1 2 (AC)(AB)(sin A) B) A = 1 2 (AC)(BC)(sin A) C) A = 1 2 (BC)(BD)(si
Juliette [100K]

Answer:

The correct option is A.

Step-by-step explanation:

Let the vertices of the triangle be ABC.

Draw a perpendicular on AC from B. The height of triangle is represented by the altitude from B.

\sin A=\frac{BD}{AB}

AB\sin A=BD

Area of the triangle is

A=\frac{1}{2}\times base\times height

A=\frac{1}{2}\times (AC)\times (BD)

A=\frac{1}{2}\times (AC)\times (AB)\sin A

A=\frac{1}{2}(AC)(AB)\sin A

Therefore option A is correct.

The value of y or how do I solve it​
Leviafan [203]

Answer:

Since it's a straight line, hence the sum of both angles must be 180°

now,

(2y + 1) + (5y - 3) = 180°

now by solving above equation u can get the value of y!

The ratio of the angles of a triangle is 5:2/3:1. what are the measures of all three angles​
Art [367]

The ratio of the angles of a triangle is 5: 2/3: 1 Then the measure of all three angles are 135, 18, 27 respectively.

<u>Solution:</u>

Given that, the ratio of the angles of a triangle is 5: \frac{2}{3}: 1

We have to find what are the measures of all three angles.

Let us suppose, "x" is the highest common factor of three angles.

Then, the three angles will be 5x, \frac{2}{3}x, x

Now, we know that, sum of angles of a triangle equals to 180

\text { Then, } 5 x+\frac{2}{3} x+x=180

\begin{array}{ll}{\rightarrow} & {6 x+\frac{2}{3} x=180} \\\\ {\Rightarrow} & {x\left(6+\frac{2}{3}\right)=180} \\\\ {\Rightarrow} & {x\left(\frac{6 \times 3+2}{3}\right)=180} \\\\ {\Rightarrow} & {x\left(\frac{18+2}{3}\right)=180} \\\\ {\Rightarrow} & {x \times \frac{20}{3}=180} \\\\ {\Rightarrow} & {x=180 \times \frac{3}{20}} \\\\ {\Rightarrow} & {x=9 \times 3=27}\end{array}

So, the three angles will be,

5x = 5 \times 27 = 135\\\\\frac{2}{3} \times 27 = 18\\\\x = 27

Hence, the angles of the triangle are 135, 18, 27 respectively.
