Answer:
26, 68 and 84
Step-by-step explanation:
Let the angle that is three times smaller than another be X.
Since the angle sum of a triangle is 180 degrees, we can form the following equation:
X + 3X + (3X- 16) = 180
Now we can simplify this equation:
7X - 16 = 180
7X = 196 (add 16 to both sides)
X = 196/7
X = 28
Therefore, the smallest angle is 28 degrees.
And from here we can figure out the other angles as they are 3x28 and 3x28 - 16.
So the three angles are 28 degrees, (3x28-16) 68 degrees, and (3x28) 84 degrees.
To make it easier, we’ll solve for x, as you do.
To get rid of 3, add 3 to both sides.
5x < 15
Now divide by 5.
x < 3
x is less than 3.
Some integers that satisfy this equation are:
2, 2.9, -10, and anything else below the number 3.
First you subtract 3 from both sides. 3-3 and 7-3, that cancels out 3 which leaves you with r>4.
Hey!
Area is equal to length × width. First find the area of the rectangle.
The area of the rectangle is 14.04 mm². That means the area of the square is also 14.04 mm². In a square, all 4 sides are the same. The length and width are the same.
