Answer:

x=80 deg

Step-by-step explanation:

It is known that the sum of the 3 angles of a triangle is equivalent to 180 deg (As the Triangle Sum Thm states). Therefore:

70+30+x=180

100+x=180

Subtract 100 from both sides to get x on one side, by itself:

100-100+x=180-100

Solve:

x=80 deg

Answer: tan(14x)

Step-by-step explanation:

Consider the Sum Formula for tan:

$tan(A + B)=\dfrac{tan(A)+tan(B)}{1-tan(A)(tan(B)}\\\\\\tan(9x+5x)=\dfrac{tan(9x)+tan(5x)}{1-tan(9x)(tan(5x)}\\\\\\\large\boxed{tan(14x)}=\dfrac{tan(9x)+tan(5x)}{1-tan(9x)(tan(5x)}$

Work out the perimeter of the triangle when the sides are : 3x-5 2x 19-x

mr Goodwill [35]

Answer:

4x + 14

Step-by-step explanation:

The perimeter of the triangle is equal to the sum of its three sides.

The sides of the triangle are 3x-5, 2x, and 19-x.

Calculate their sum.

3x - 5 + 2x + 19 - x

Rearrange.

3x + 2x - x + 19 - 5

Add or subtract like terms.

4x + 14

The perimeter of the triangle is 4x + 14.
