Answer 1

Answer:

The Value of x is 40.

Step-by-step explanation:

Given:

∠SRT ≅ ∠STR

∠SRT = 20

m∠SRT = 4x

To find: Value of x

Solution:

From the given data,

m ∠SRT = 20

Also ∠SRT ≅ ∠STR

Hence from congruence and equality property we can say that;

m∠STR= 20

m∠STU= 4x

Now by straight angle property which states that sum of two angles which are created by a straight line is always 180.

Hence,

∠STR +∠STU =180

Now Substituting the given values we get;

$20+4x=180\\4x=180-20\\4x=160\\\\x=\frac{160}{4} =40$

Hence m∠STU = 4x =4 ×40 = 160°

Hence the value of x = 40.
