Question

Find The Value of X
​

Answer 1

Answer:

x=17

Step-by-step explanation:

Given that <p=60° < q=60° and <R=3 x+9 °

we know that angle sum property .sum of all angles of a triangle=180°

so,60+60+3x+9=180°

120+9+3x=180°

129+3x=180

3x=180-129

3x=51

x=51/3

x=17

now angle R is 3x+9 = 3(17)+9

=51+9

=60°

therefore<r=60° and x=17
