Answer:
Step-by-step explanation:
y = 12x
12x = y
x = y/12
Answer:
-6
Step-by-step explanation:
x+56+x+136=180
2x+192=180
-192 -192
2x=-12

Answer:
a, b, and c can be formed a triangle
The area of the triangle is 13385.87 square units.
Step-by-step explanation:
<em>Let us revise an important fact in any triangle</em>
- The sum of the lengths of the two shortest side must be greater than the length of the longest side
The length of the sides are a = 240, b = 132, and c = 330
∵ The two shortest sides are a = 240 and b = 132
∵ a + b = 240 + 132 = 372
∵ The longest side is c = 330
∵ 372 > 330
∴ a + b > c
∴ a, b, and c can be formed a triangle
<em>Let us revise the </em><em>Heron's formula</em><em> of the area of the triangle</em>
- Area = , where a, b,c are the lengths of the sides of the triangle, and
∵
∴
∴
∴
The area of the triangle is 13385.87 square units.
