Use the Law of Sines for this one: 26/sin 55 = 28/sin A; 26 sin A = 28 sin 55;
sin A = 28 sin 55/26; sin A = 22.9362/26; sin A = .88216, and inverse sin(.88216) = 61.90

Answer: 270 cubic centimeters
Step-by-step explanation:
bh/3 is the formula so...
because it's a right triangle we multiply the legs together:
9*12 = 108
and we divide by 2
108/2 = 54
height is 15
(15*54)/3 = 810/3 = 270
Our answer is 270 cubic centimeters.
The 2 little lines on each side of the triangle mean that the two sides are equal.
Because the two sides are equal the two bottom inside angles are also the same.
The left bottom angle is given as 68, so the bottom right is also 68.
The three inside angles of a triangle need to equal 180.
So X = 180 - 68 - 68
X = 44
