Answer:

  A.  three angles measuring 25, 65, and 90

Step-by-step explanation:

For any triangle to be formed, the sum of angles must be 180° and the lengths of the sides must satisfy the triangle inequality (the sum of the two shortest sides is at least the length of the longest side).

A triangle can be formed only by selections A, C, and D. The triangles formed by the specification of 3 sides are unique. (That is why we can have SSS congruence.) So selections C and D will not form more than one triangle.

The triangle formed by three given angles (and no given side) will not be unique. (That is why we cannot have AAA congruence; only AAA similarity.) Many different triangles can be formed having these angles.

The appropriate choice is selection A.

Triangle ABC is a right triangle. If AC =7 and BC=8, find AB . Leave your answer in simplest radical form.
almond37 [142]

Answer:

AC=\sqrt{15\\

Step-by-step explanation:

AC is the base, BC is the hypotenuse, so the side length is AB.

We are given that AC=7 units, and BC is equal to 8.

Thus we have 8^2-7^2=(AB)^2

64-49=(AC)^2

15=(AC)^2

AC=\sqrt{15\\

The length of a rectangle is three more than twice the width. Find the width and the length if the perimeter is 84 f
Naddik [55]

\text{Hello! :D}

\boxed{\text{width = 13ft, length = 29ft}}

\text{ Let the width = "w":}\\\\\text{Write an expression to represent the length in terms of "w":}\\\\l = 2w + 3\\\\\text{Formula of a rectangle: } \\\\P = 2l + 2w\\\\\text{Therefore:}\\\\84 = 2(2w + 3) + 2(w)\\\\84 = 4w + 6 + 2w\\\\84 = 6w + 6\\\\\text{Subtract 6 from both sides:}\\\\78 = 6w\\\\\text{Divide both sides by 6:}\\\\78/6 = 6w/6\\\\w = 13ft\\\\\text{Plug this value of "w" into the equations for the length:}\\\\l = 2(13) + 3\\\\l = 26 + 3\\\\l = 29ft

35.) The temperature of dry ice is -109.3°F.
kari74 [83]

Hello there!

You're given the value of -109.3°F, and you are told that is 184.9°F less than the outside temperature. To find the outside temperature, add the difference to the temperature of dry ice.

-109.3°F + 184.9°F =75.6°F

So, the outside temperature is 75.6°F. I hope this was helpful, have a great rest of your day!

The given trinomial can be factored using factorization as

x²-x-12
=x²-4x+3x-12
=x(x-4)+3(x-4)
=(x-4)(x+3)

Thus x-4 and x+3 are the factors of the given trinomial. From these we can see x+3 is listed in option A

So the answer to this question is Option A
