The answer to this question would be: B. JK and LM meet at a right angle.

The reversed T symbol in this question means "perpendicular". That means the JK and LM line have 90-degree angle difference. A straight angle is 180 degree and right angle mean 90 degrees.
A perpendicular line should be in the same plane and intersect each other.

Vesna [10]

Answer:

$Cranberry:Apple:Orange = 7:5:8$

Step-by-step explanation:

Given

$Apple = 1/4$

$Orange = 2/5$

Required

Determine the ratio of Cranberry to Apple to Orange

First, we calculate the fraction of Cranberry using:

$Cranberry + Apple + Orange = 1$

Substitute values for Apple and Orange

$Cranberry + 1/4+ 2/5= 1$

Collect Like Terms

$Cranberry = 1- 1/4- 2/5$

Take LCM

$Cranberry = \frac{20 - 5 - 8}{20}$

$Cranberry = \frac{7}{20}$

The ratio is then represented as:

$Cranberry:Apple:Orange = 7/20:1/4:2/5$

Multiply through by 20

$Cranberry:Apple:Orange = 20(7/20:1/4:2/5)$

$Cranberry:Apple:Orange = 20*7/20:20*1/4:20*2/5$

$Cranberry:Apple:Orange = 7:5:8$
