Question

find the value of x in each of the following given triangles​

Answer 1

Answer:

(3x+1)°+(4x+5)°+90°=180°                                         (angle sum property of a                           triangle)

3x°+1°+4x°+5°+90°=180°

3x°+4x°+5+1°+90°=180°

7x°+96°=180°

7x°=180°-96°

7x°=84°

x°=84/7°

x°=12°

∴(3x+1)°=(3*12+1)°=37°

∴(4x+5)°=(4*12+5)°=53°

Answer 2

Answer:

x=12

angle P=37°

angle R=53°

Step-by-step explanation:

90+(3x+1)+(4x+5)=180

7x+6=180-90

7x=90-6

x=84/7

x=12

angle P=3x+1

=3*12+1

=37°

angle R=4x+5

=4*12+5

=53°

x=12

angle P=37°

angle R=53°
