72 + 74 is 146.
The angle sum of a triangle is 180.
180 - 146 is 34.
The answer is 38 degrees because for every triangle, the angles add up to 180 and the small square on the triangle represents it is a right triangle, which has 90 degrees. 38 + 52 + 90 = 180
Answer:
The smaller number is 12 & greater number is 15.
Answer:
50
Step-by-step explanation:
The perimeter of a Triangle is the sum of it's 3 sides.
We are given two sides here which is side length 5.6 and a side of length 19.7
Let's us represent the third side as x
Therefore
x + 19.7 + 5.6 = Perimeter of the triangle
We would have this equation
But it is important to know that every side of a triangle must be less than the sum of the other two sides, hence
x < 19.7 + 5.6
x < 25.3
Adding 25.3 to both sides to make the left side equal to the perimeter
perimeter = x+25.3 < 25.3 + 25.3 = 50.6
Therefore, 50.6 is the smallest whole number that is larger than the perimeter of the triangle in the question above.
Therefore, the biggest whole number smaller than the perimeter of the above triangle is 50
