One leg of a 45 - 45 - 90 triangle measures 12 centimeters what is the length of the hypotenuse
adelina 88 [10]
The angles of the triangle are given as to have measures of 45°-45°-90°. This entails that the triangle is an isosceles triangle where the 2 legs of the triangle are of equal length. We calculate as follows:

c² = a² + b²

c² = 2a²

4² = 2a²

a = 2√2

Cloud [144]

Answer:

80 countries participated in the 1980 olympics in Moscow.

Step-by-step explanation:

Hello, I think I can help you with this

You can solve this by using a simple rule of three

Step 1

define

140 countries participated in 1984,this was 75% more than the last time,this means that 140 is the 175% of a value that we need to know

if

140 ⇔175%

x?    ⇔100%

the relation is

\frac{140}{175}=\frac{x}{100}

Step 2

solve for x

\frac{140}{175}=\frac{x}{100}\\x=\frac{100*140}{175}\\x=\frac{14000}{175} \\x=80

80 countries participated in the 1980 olympics in Moscow.

Have a nice day
