Pretty sure it’s company C. Don’t 100% take my word tho. I was always told that with problems like this u always pick the lowest number.
Answer:
147

Answer:
The size of the angle formed at the top of the sail is 35.
Step-by-step explanation:
We know that the sum of all angles inside a triangle must be 180. This is a rule.
So we know that a right triangle is called like that because one angle is a 90-degree angle.
Then we have that:
180 = right angle + lower edge angle + angle top of the sail
180 = 90 + 55 + angle top of the sail
Solving for 'angle top of the sail' we have:
angle top of the sail = 180 - 90 - 55 = 35
The size of the angle formed at the top of the sail is 35.
The lenght of each side is 24cm, 24cm, and 8cm.
In order to solve this problem, we know that the perimeter of a triangle equation is P = a + b + c, where a, b, and c are the sides of the triangle.
The perimeter is 56cm, we can write the equation as follow:
a + b + c = 56cm (1)
If each of the two longer sides of the triangles is three times as long as the shortest side, we can assume:
c = shortest side = x
a = b = longer sides = 3x
Substituting the values in the equation (1):
3x + 3x + x = 56cm
7x = 56cm
x = 56cm/7 = 8cm
c = shortest side = 8cm
a = b = longer sides = 3(8cm) = 24cm
