Answer:
Pretty sure it's 20.24.
Step-by-step explanation:
Since you know the side adjacent to the reference angle and you want to find the side opposite, you're going to need to use tangent, which is opp/adj.
tan(39) =
Find the tangent of 39...
0.8097 is the approximate value. So...
0.8097 =
Now, switch the sides to make it easier.
= 0.8097
Multiply both sides by 25.
x = 20.24
The value of x will be equal to x = 79.
<h3>What is the triangle?</h3>Triangle is a shape made of three sides in a two-dimensional plane. the sum of the three angles is 180 degrees.
For an isosceles triangle, the value of two opposite angles is equal and the opposite sides are also equal.
The Sum of the three angles is equal to 180 degrees so the third angle will be calculated as:-
Angle = 180 - 142 - 19 = 19
Now applying Lami's theorem in the triangle we will get the third side.
x = 79
Therefore the value of x will be equal to x = 79.
