Answer:
Step-by-step explanation:
In the given trianle all sides are equal. So, it is equilateral triangle.
So,each angle is 60
Reason for x = 60,
Two lines are parallel. So alternate interior angle are equal.
Answer:
The sum of all integers is 774.
Step-by-step explanation:
Since √11 = 3.3166, and 3.3166 is not an integer, so the first integer is 4.
From 1 to 39, there are 39 integers. But we started with 4, so we take out 3 numbers (1, 2, 3). Therefore, there are 39 - 3 = 36 numbers left.
The total number between 4 and 39 is 36 = n.
Sn = n/2 x (a1 + an)
S36 = 36/2 x (4 + 39) = 18 x 43 = 774

Answers:
scalene (column 1)
right triangle (column 2)
==============================================
Explanation:
The lack of tickmarks tells us indirectly that none of the sides are equal to one another. So all three sides are different lengths. Therefore, the triangle is scalene. This rules out "equilateral" and "isosceles".
The small square marker indicates we have right angle, aka 90 degree angle. In turn, it leads to the fact we have a right triangle. This rules out "acute" because acute triangles have all three angles smaller than 90. We can also rule out "obtuse" because obtuse triangles have one angle larger than 90.
In short, this triangle is both scalene and a right triangle. We can call it a right scalene triangle, or a right triangle that is scalene.
