Triangle ABC has side lengths:

AB = 3.5 cm, BC = 2.4 cm, and AC = 4.2 cm

ΔABC ≅ ΔHJK

What is the length of side HJ?

HJ =
cm

Step-by-step explanation:

where does hj come form because a triangle only has 3 sides which Is ABC isn't it.

its 3.5cm

Step-by-step explanation:

AB=HJ which makes them both 3.5cm

there are no short passages to look at

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
