Someone Help Pls Find The Value Of X In The Triangle Shown Below class=

Sagot :

Answer:

Step-by-step explanation:

Remark

2 of the sides are equal. That means that the two angles opposite the equal sides  are equal as well.

Every triangle has 180 degrees

Solution

The unmarked angle = 61 degrees

x + 61 + 61 = 180                 The three angles add to 180

x + 122 = 180                       Subtract 122 from both sides

x + 122-122 = 180 - 122       Combine

x = 58
