Which descriptions can describe more than one triangle? check all that apply
babunello [35]

Answer:

Angle measurements of 35°, 35°, and 110°

Angle measurements of 40°, 60°, and 80°

Step-by-step explanation:

If you specify only the three angles, you can have an infinite number of similar triangles of different sizes.

A is wrong. There can be only one triangle in which all three side lengths are specified.

C is wrong. The angles do not add up to 180°.

Ray Of Light [21]
Cindy is 72 inches long. Imagine it like a right triangle. Her shadow is the base, she is the side, and the distance between her head and the end of the shadow is the diagonal line connecting the two. Use the Pythagorean theorem to find how tall cindy is.

a²+b²=c²        a=21, the length of the shadow
                       b= ? cindy's height
                     c= 75, the distance from her head to the edge of the shadow
21²+ b²=75²
441 +b² = 5625
-441         -441
------         -------
  0             5184
b² = 5184
√b² =√5184
b= 72

consider the following.find formula simplify answer .Find the domain for the formula and round answer to two decimal places if n
Elanso [62]

The sum of functions is given as:

(f+g)(x)=f(x)+g(x)

In this case we have:

(f+g)(x)=5x+\sqrt[]{x-1}

The domain of the functions is any number that makes the squared root a real number, then:

\begin{gathered} x-1\ge0 \\ x\ge1 \end{gathered}

Hence the domain of the functions is:

\lbrack1,\infty)
