Answer:
x = 16
Step-by-step explanation:
SR = ST ⇒ Two sides are equal. So, ΔSRT is an isosceles triangle.
The angles opposite to equal sides are equal.
⇒ ∠STR = ∠R
∠STR = 4x - 28
Linear pair: If a ray stands on a line, then the adjacent angles are supplementary and they are called linear pair
∠STR + ∠STU = 180° {linear pair}
4x - 28 + 9x = 180
4x + 9x - 28 = 180 {Combine like terms}
13x- 28 = 180
Add 28 to both the sides
13x = 180 + 28
13x = 208
Divide both sides by 13
x = 208/13

1/2 -3/6 is equal to 0 because 1/2 is equal to 1/2
To evaluate when plugging in numerical values for variables, simply put the numerical values in the place of the corresponding variables:


♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫
➷The answer is that there is a right angle(90 degrees) and also there are three sides.
Explanation: Since all right triangles have a right angle, and also is a triangle, they have three sides and one is 90 degrees.
