Ответ:
Yes it is the right angle triangle
Step-by-step explanation:
In right angle triangle hypotenuse is equal to sum of perpendicular and base
(H) ^2 = P ^2 + B ^2
(4.5) ^2 = (2.7) ^2 +(3.6) ^2
20.25 = 7.29 +12.96
20.25 = 20.25
Hence, it is right angle triangle .
Ответ:
You first subtract 15.2 on both sides because you need to get rid of the 15.2. 15.2-15.2=0 and you would be left with the answer L= -19.7
