Answer:
The triangle has three acute angles, so it is an acute triangle. The triangle has two congruent sides, so, it is an isosceles triangle. It is an acute isosceles triangle.
Step-by-step explanation:
Number of ways of picking a smaller number out of a bigger number is called combination.
Number of way of picking 3 stamps out of 4 is 4C3 (4 combination 3) = 4! / (3! x (4 - 3)!) = 4! / (3! x 1!) = (4 x 3 x 2 x 1) / (3 x 2 x 1 x 1) = 24 / 6 = 4 ways.
Both the angles will be 105°
Just add up the given angles, subtract the result by 360, and divide by 2.
Answer:
Total people = 240
Step-by-step explanation:
Let the total number of people by 'x'.


Number of children = 100
When we subtract the total number of men and women from the total people 'x', we get the number of children.



x = 20 * 12
x = 240
<h3> Total number of people = 240</h3>
Answer:
9.2
Step-by-step explanation:
Since it is a right triangle, you can use the Pythagorean theorem to find the third side which is the hypotenuse.
a^2 + b^2 = c^2
7^2 + 6^2 = c^2
49 + 36 = c^2
85 = c^2
9.219 = C
So, the answer rounded to the nearest tenth would be: 9.2
