The area of triangle PQR is 100 cm?. 25 cm
Q
o
16 cm
R
Calculate the missing angle, 0.

30

Step-by-step explanation:

area of triangle =1/2×sino×25×16

100=200sino

100/200=sino

sino=1/2

sino=sin30

o=30°

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
