A straight angle is a straight line. A straight line measures exactly 180 degrees.
Answer:
The area is 10
Step-by-step explanation:
The blue area can be divided into a square and a number of triangles, but it is just as easy to subtract the areas of the triangles around the outside:
The blue area is ...
16 -1 -1 -1 -2 -1 = 10 . . . . . . (CCW from upper left)
Also you can count the number of dots between each curve
Right and scalene. A right triangle has an angle that measures to be 90° and using the pythagorean theorem, we know that the triangle is scalene, meaning that all three sides have different side lengths. (:
3² + 4² = 5²
Answer:
The value of y is y=15
Step-by-step explanation:
We have:
AB = 6y – 3, BC = 4y – 5, and CD = 7y – 18
We define the isosceles trapezoid as it has two opposites parallel, the two other opposites legs are equal and also the diagonals are equal.
Here AB = CD
6y-3 = 7y-18
Combine the like terms:
18-3 = 7y-6y
15 = y
It means the value of y is y=15....
