What is the value of x????

inysia [295]

If QR is a median, then:

$\dfrac{NO+MP}{2}=QR$

We have NO = 30, MP = 9x - 42 and QR = x + 15. Substitute:

$\dfrac{30+9x-42}{2}=x+15\qquad\text{multiply both sides by 2}\\\\9x-12=2x+30\qquad\text{add 12 to both sides}\\\\9x=2x+42\qquad\text{subtract 2x from both sides}\\\\7x=42\qquad\text{divide both sides by 7}\\\\\boxed{x=6}$

2<br> 1<br> X 46<br> 7. Find the m 2 JKL<br> in rhombus JKLM

almond37 [142]

Step-by-step explanation:

since KLJ is a parallelogram, it can be split into 2 congruent triangles, as seen above. The angles remain the same, so we know angle KJL is also 25 degrees. Using the triangle angle sum theorem (all sides of a triangle add up to 180 degrees), we can determine the missing angle measure is 25 degrees. It would have been nice if the question told us JKLM was also a rhombus.
