Question

Find the value of unknown x in the following figure:

​

Answer 1

Answer:

Step-by-step explanation:

right angle =180-5= 175 so x=175 divide5 =35 -5=30 ans

Answer 2

Answer:

sum of three angles of a triangle is =180°

then,

=5x+x+90°=180°. (anglePQR=90°, right angle triangle)

=6x+90°=180°

=6x=180°-90°

=6x=90°

=x=90°/6

x=15

so, angle PRQ=15°

now,

angle QPR=5x

then, putting value of x in the equation,

angle QPR=5×15=75

so, angle QPR=75°
