Answer:
D.39
Step-by-step explanation:
Pythagorean Theorem: a^2+b^2=c^2 (Where a and b are the legs of the triangle and c is the hypotenuse)
Using this:
(AB)^2+(AC)^2=(BC)^2 (Pythagorean theorem)
15^2+36^2=(BC)^2 (Substitution)
225+1296=(BC)^2
(BC)^2=1521
BC=39
Answer:
D. 39
Step-by-step explanation:
The three interior angles of a right triangle always have a sum of 180°, and right angles always equal 90°.
Adding the angles shown here,
36+15+90 = 141
And, 180 - 141 = 39°.
Therefore, the length of angle BC is 39°.
