Answer: Weeeell, 35

Step-by-step explanation:

1. By definition, the perimeter of a triangle is the sum of the lenght of each side.

2. Then, the perimeter of the triangle LMK is:

P_{LMK}=14+17+11\\P_{LMK}=42

3. If both triangles are congruent and the scale factor is 5:6 (Which you can rewrite as a fraction: 5/6), you must multiply the perimeter of the triangle LMK by this scale factor.

4. Then, you have that the perimeter of the triangle GHJ is:

P_{GHJ}=42*\frac{5}{6}=35

I need help :(( please please ease triangle area ?

kvasek [131]

Answer:

$\frac{25\sqrt{3}}{2}$

Step-by-step explanation:

The area of a triangle is given by $A=\frac{1}{2}bh$ where $b$ is the base of the triangle and $h$ is the height of the triangle. In a right triangle, the two legs will represent the base and height, both interchangeable.

In a 30-60-90 triangle, the sides are in the proportion $x:x\sqrt{3}:2x$ , where $2x$ is the hypotenuse of the triangle and $x$ is the side opposite to the 30 degree angle. Since the hypotenuse of this triangle is given as 10, the leg opposite to the 30 degree angle is equal to $10\div 2=5$ and the leg adjacent to the 30 degree angle is equal to $5\sqrt{3}$ .
