A triangle has sides 12, 35, and 37. Identify whether the triangle is right, acute, or obtuse.

s2008m [1.1K]

Answer:

Right triangle

Step-by-step explanation:

Using pythagorean theorem,

$c^2 = a^2 + b^2\\37^2 = 12^2 + 35^2 \\1369 = 144 + 1225\\1369 = 1369$

Hence satisfied. So it is right triangle.

Can someone help me please <br><br> A) tanL =<br> B) sinN= <br> C) cosN=

timofeeve [1]

Answer:

a.) tanL= 0.533

b.) sinN= 0.882

c.) cosN= 0.471

Step-by-step explanation:

Triangle ABC is similar to Triangle LMN, which means that their corresponding angles are congruents.

Using SOH-CAH-TOA we have,

tanL~tanA= 8/15 = 0.533

sinN~sinC= 15/17 = 0.882

cosN~cosC= 8/17 = 0.471
