Which type of triangle has side measures of 6 cm, 7 cm, and 12 cm and one angle with a measure of 120°? a)acute isosceles b) right scalene c) obtuse equilateral obtuse scalene

First here we are given all sides of different length 6cm , 7cm and 12cm.

A scalene triangle has the property that all its sides are different.

So this confirms the triangle is scalene for sure.

Now the other information given is one angle is 120 degrees.

120 is an obtuse angle.

So combining the two properties we may say that the triangle is obtuse scalene.

last option obtuse scalene is correct .

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
