Triangle PQR has right angle Q. If sin R = 
, what is the value of tan P?
The correct answer is: 0.6
○ Triangle with one angle of 90॰ is called right angle triangle.
○ Side opposite to 90॰ is called Hypotenus.
○ Pythagoras theorem, according to which (side)2 + (side)2 = (hypotenus)2
○ In right angled triangle,
- Step by step explanation:
○ Given:
In △PQR,
○ Step 1:
We know that, in right angle triangle
According to pythagoras theorem,
PQ2 + RQ2 = PR2
∴ 42 +RQ2 = 52
16 +RQ2 = 25
RQ2 = 25 - 16
RQ2 = 9
RQ =
RQ = 3
○ Step 2:
○ We know that,
- Final Answer:
Hence, the = 0.6
