Answer:
-2
Step-by-step explanation:
-6 - (-4)
Subtracting a negative is like adding
-6 +4
-2
Answer:
Step-by-step explanation:
This is a isosceles triangle, An isosceles triangle is a triangle with (at least) two equal sides. In the figure above, the two equal sides have length and the remaining side has length.
A scalene triangle is a triangle in which all three sides have different lengths. Also the angles of a scalene triangle have different measures.
In geometry, an equilateral triangle is a triangle in which all three sides have the same length. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.
Answer:
1) 35
Step-by-step explanation:
1. First, you have to realize that a straight line is 180 degrees.
Why is this important to know? Well you know that all angles of a triangle added up together HAS to equal 180, it'll be a straight line
2. Add 40 and 105, this gives you 145.
3. Subtract 145 from 180, and you should get 35, which is x.
You can check this by adding 40, 105, and 35 together.
3/10 plus 1/2 equals 8/10
