Answer:
Surface area= 7.5
Step-by-step explanation:
The area of a triangle is b*h/2. so if you fill in the numbers your equation would be 5*3/2. 5*3=15 and 15/2=7.5
hope this helps!!
The x coordinate stays the same but y coordinate changes sign so it will be a reflection in the x-axis.
Contradictions usually mean they go against established rules. Squaring a negative number is one example if it is in math. But just think of anything that goes against what is known.
As 1 yard is equal to 3 feet , so 4 yard will be 12 feet !
so 13 foot > 4 yards
No the sum of measures would exceed 180, therefore it would not be a obtuse triangle
