Step-by-step explanation:
Answer:
y = 14.5
Step-by-step explanation:
given that y varies directly as x
mathematically,
y ∝ x
y = kx .............................................. where k is the constant of proportionality.
k = y /x
given that
y = 79
x = 49
k = 79/49
k = 1.61
to find y when x = 9
from
y = kx
y = 1.61 × 9
y = 14.5
therefore the value of y when x = 9 in ths variation is evaluated to be equals to 14.5
Hi
QPR = 74 (vertically opposite angles)according to angle sum property which means if we add all the angles of triangle we get 180 degrees
So,
PQR=180-(74+51)
180-125=55
So answer is 55 degrees
