Find the perimeter of OQR if OQ=6.5.<br> A.<br> 6.1<br> B.<br> 12.2<br> C.<br> 13<br> D.<br> 19.1
Svetach [21]

ANSWER


The correct answer is 19.1


EXPLANATION


The perimeter of triangle OQR is the sum of the distance around the triangle.



Thus,


Perimeter=|OQ|+|OR|+|RQ|



We can observe that two of the angles are equal.



The angles that are equal measures 62° each.



Therefore triangle OQR is an isosceles triangle. This means that



|OQ|=6.5=|OR|



Hence,



Perimeter=6.5+6.5+6.1




Perimeter=19.1 units.

What are the solutions of the quadratic equation (x – 8)2 – 13(x – 8) + 30 = 0? Use u substitution to solve.
Dafna11 [192]
It is a quadratic
where x-8 is the squared term
do
x-8=u

u^2-13u+30=0

solve
u=\frac{-b+/- \sqrt{b^2-4ac} }{2a}
u=\frac{-(-13)+/- \sqrt{(-13)^2-4(1)(30)} }{2(1)}
u=\frac{13+/- \sqrt{169-120} }{2}
u=\frac{13+/- \sqrt{49} }{2}
u=\frac{13+/- 7 }{2}
u=\frac{20} }{2} or u=\frac{6 }{2}
u=10 or 3

10=x-8 or 3=x-8
18=x or 11=x

x=11 and/or 18
