From the figure, how many square units are the area of ​​a triangle xwy when yw=zw? A. 1.84
B. 1.42
C. 0.42
D. 0.84

0.42

Step-by-step explanation:

→ Use Pythagoras to find YZ

√2.5² - 0.7² = 2.4

→ Half the answer to find YW

2.4 ÷ 2 = 1.2

→ Substitute the values into the formula for the area of a triangle

0.5 × 0.7 × 1.2 = 0.42

step-by-step explanation:

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).
