Answer:
area of an obtuse-angled: 14 cm²
explanation:
<u>using the formula:</u>
note: the formula for finding area is same for all obtuse triangle.
A (10,4)
Midpoint (6,0)
B (2, -4)
Part A:I found it by using a Pythagorean theorem.The answer is 15 cm.
8∧2+x∧2=17∧2
X=sqrt(17∧2-8∧2)
X=Sqrt(225)
X=15 cm
Part B:Will be the answer of a lateral area of a prism.The answer is 1000 cm2.
lateral area = perimeter of triangle * height of prism
lateral area = (16 + 17 + 17) * 20
lateral area = 50 * 20
lateral area = 1,000 cm<span>2</span>
