Answer:

3 in

Step-by-step explanation:

Sum of all sides of ∆ = perimeter

Given that it has a perimeter of 13 in, and the following sides: (x - 5) in, x/2 in, and 6 in, therefore:

x - 5 + \frac{x}{2} + 6 = 13

Solve to find the value of x

\frac{2x - 10 + x + 12}{2} = 13

\frac{3x + 2}{2} = 13

Multiply both sides by 2

\frac{3x + 2}{2}*2 = 13*2

3x + 2 = 26

Subtract 2 from both sides

3x + 2 - 2 = 26 - 2

3x = 24

Divide both sides by 3

\frac{3x}{3} = \frac{24}{3}

x = 8

The shortest side = (x - 5) in

Plug in the value of x

= (8 - 5) in

= 3 in

Please help on this triangle
Arte-miy333 [17]

Answer:

h ≈ 13.4

Step-by-step explanation:

Since the triangle is right we can use the sine ratio to find h

sin48° = \frac{opposite}{hypotenuse} = \frac{h}{18}

Multiply both sides by 18

18 × sin48° = h

⇒ h = 13.4 cm ( to 1 dec. place )
