Answer:
There is no way to determine who drew this, unless there is a picture of their drawings.
It will though be easy to determine.
Think of the letter T turned upside down, the angle the vertical line makes with the horizontal line is 90 degrees. Bending the vertical line to the right hand side, the angle on the left hand side is above 90 degrees, and the one on the right hand side is below 90.
And a triangle with a 90 degrees angle is called right angled.
5 friends contribute x money to go to a cart that costs $100.
.
5x = 100
x = 100/5
x = 20
.
Each friend contributed $20 for the cart
Answer:
no solutions
Step-by-step explanation:
The lines are parallel and never intersect. The solutions occur when the lines intersect, so there are no solutions
Answer:
The correct figure is B.
Step-by-step explanation:
The statement provided is:
"If it is an equilateral triangle, then it is an isosceles triangle"
The contra-positive of a statement is determined by switching the hypothesis and conclusion of the provided statement and negating both.
Then the contra-positive of the statement provided will be:
- Switching the hypothesis and conclusion:
If it is an isosceles triangle - It is an equilateral triangle.
- Negating both the statements:
If it is not an isosceles triangle - it is not an equilateral triangle.
Thus, the contra-positive of the statement is:
"If it is not an isosceles triangle, then it is not an equilateral triangle."
Thus, the correct figure is B.
