muminat

Answer:

2\frac{1}{2}  inches

Step-by-step explanation:

The "x" represents the number of buttons.

There are 2 sizes longer than 1 inch:

1\frac{1}{8} in  and  1\frac{1}{4} in

There are NO 1  1/8 inch buttons

THere are two 1  1/4 inch buttons

Hence the combined length would be:

1\frac{1}{4}+1\frac{1}{4}=2\frac{2}{4}=2\frac{1}{2} inches

Find the perimeter of a 30°-60°-90° triangle with a hypotenuse of 18. a.P=27 +9/3^- c.p=24+6/3^- b.P= 27+9/6^- d. P=24+3/6^-
DIA [1.3K]

note that for a 30°-60°-90° triangle , the sides are 1, √3, 2

If the hypotenuse (2) is equal to 18, find the other lengths

First, find side (1). Divide 18 by 2

18/2 = 9

Next, multiply 9 with √3

9(√3) = 9√3

Finally, find the perimeter. Add all sides:

P = 18 + 9 + 9√3

P = 9√3 + 27

hope this helps
