On the left side you need to distribute that 2 into (x+3). On the right side distribute 3 into (2x+1). Combine like terms and set the entire equation equal to zero, then methodically find x. leave a comment if you need more help.

The third angle of an isosceles triangle is 16 o less than the sum of two equal angles. Find
vodka [1.7K]

Answer:    49°, 49°, 82°

<u>Step-by-step explanation:</u>

Let x represent the base angles

then 2x - 16 is the vertex angle.

Triangle Sum Theorem states that the sum of the angles is 180°

(x) + (x) + (2x - 16) = 180

                 4x - 16 = 180

                       4x = 196

                         x = 49

Base angles: x = 49

Vertex angle: 2(49) - 16 = 82

In triangle EFG , EF=FG . EF= 6X-10 , EG =2X+14, and FG =3X+11. find EF .
jarptica [38.1K]
Since EF=FG, you can set 6x - 10 = to 3x +  11

6x -10 = 3x +11

Then add like terms

6x - 3x = 11+10

so, 3x = 21

Now you can divide by 3 to get x = 7 :)

then put it back into 6x - 10

6(7) - 10 = EF

so, EF = 32
