Answer:
- area: 114 square units
- perimeter: 44 units
Step-by-step explanation:
The figure is a trapezoid with bases 12 and 7, and a height of 12. The area formula is ...
A = (1/2)(b1 +b2)h
A = (1/2)(12 +7)(12) = 114 . . . square units area
__
The length of side AB can be found using the distance formula:
d = √((x2 -x1)^2 +(y2 -y1)^2)
d = √((6 -(-6))^2 +(1 -6)^2) = √(144 +25) = 13
The sum of the side lengths is then ...
13 +7 +12 +12 = 44 . . . units perimeter

Answer:
The BEST statement describes how the triangle could be altered in order to make it a right triangle
B.
One inch could be removed from the 9 in. leg and a new hypotenuse could be drawn.
Step-by-step explanation:
Triangle ABC has the side lengths 6 in., 9 in., and 11 in.
The only condition is that satisfy to become Δ ABC a Right angle triangle is
Longer leg (one inch remove) = 9 - 1 = 8 inch
New hypotenuse = 10 inch
So that Pythagoras theorem must satisfy
So (Hypotenuse)² = 10² = 100
(Shorter leg)² = 6² = 36
(Longer leg)² = 8² = 64
So we have,
(Shorter leg)² + (Longer leg)² = 36 + 64
= 100
= (Hypotenuse)²
Therefore, Δ ABC is right Triangle By Converse of Pythagoras Theorem.
Therefore,
The BEST statement describes how the triangle could be altered in order to make it a right triangle
B.
One inch could be removed from the 9 in. leg and a new hypotenuse could be drawn.
Answer:
70
Step-by-step explanation:
the red lines mean the two sides are equal
so its an isosceles triangle meaning the two angles other than the 40° one are equal
the inner angles of a triangle must add up to 180
so 180-40 = 2x
140 = 2x
x = 140/2 = 70
Hey!~
In this problem, Robbie is not correct. If you multiply to see how many stickers they each have, they will both have 16. They have the same amount of stickers.
Hope this helps and have a great day!~
