Find the missing angle of a triangle with 60 degrees and 40 degrees

1 answer:

3 0

The sum of the interior angles of a triangle = 180 degrees. So, all of the angles on the inside of the triangle will add up to 180.

60 + 40 + ? = 180

100 + ? = 180

? = 80

The missing angle in the triangle is 80 degrees.

Hope this helps!

Ber [7]

Answer: $-3\sqrt{3}$

This the expression -3*sqrt(3) or "-3 times the square root of 3"

=================================================

Work Shown:

Factor each term inside the square root so that a perfect square is one of the pieces. Then break up the roots and simplify as shown below.

$-4\sqrt{12} + \sqrt{75}$

$-4\sqrt{4*3} + \sqrt{25*3}$

$-4\sqrt{4}*\sqrt{3} + \sqrt{25}*\sqrt{3}$

$-4*2*\sqrt{3} + 5*\sqrt{3}$

$-8\sqrt{3} + 5\sqrt{3}$

$(-8+5)\sqrt{3}$

$-3\sqrt{3}$
