The 3 angles of a triangle will add up to 180 degrees.
5x + 2x + 3 + 3x - 3 = 180...combine like terms
10x = 180
x = 180/10
x = 18
one angle is : 5(x) = 5(18) = 90 degrees
the other angle is : 2x + 3 = 2(18) + 3 = 39 degrees
the last angle : 3x - 3 = 3(18) - 3 = 51 degrees
you lose 9 points because you went 3 times the limit
Answer:
area of P=πr^2
area of Q=πr^2/4=π×400/4=100π
acc to ques
A(q)=4× A(p)
100π=4×πr^2.
100=4r^2
r^2=25
radius of p= √25=5cm
