Question

Someone help pls !!
find the value of x in the triangle shown below

Answer 1

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
