Answer:

Step-by-step explanation:

The angles of a linear pair are supplementary. Angles 'a' and 'b' form a linear pair. That is, ...

∠EAB + ∠BAC = ∠EAC, a straight line

Consequently, angles 'a' and 'b' are supplementary.

Step-by-step explanation:

Speed =Distance travelled/ Time

Time =Distance travelled/ Speed

T = D / 30 The time it took her to drive to Fixit.

T = D / 20 The time it took her to ride the bus home.

D / 30 + D / 20 = 1 hour, solve for D,

Which best explains whether a triangle with side lengths 2 in., 5 in., and 4 in. is an acute triangle?

Talja [164]

Answer:

The triangle is not acute because 2² + 4² < 5²

Step-by-step explanation:

The square of the hypotenuse of a right triangle with the given short sides would be 2² +4² = 20. So, that hypotenuse would be √20, about 4.47. The long side of this triangle is longer than that, so the angle opposite is larger than 90°. The triangle with sides 2, 4, 5 is an obtuse triangle.

The triangle is not acute because 2² + 4² < 5²
