Answer:
Vertical angle.
Step-by-step explanation:
The Definition of Vertical Angles is the opposite angles formed by two intersecting lines and if two angles are vertical angles, then they have equal measures (or congruent).
In the attach photo, the pair of opposite congruent angles are A&C and B&D
The original statement is true by the definition of what constitutes a right angle. It's simply set up this way.
The contrapositive would be the statement "if the angle does not measure 90 degrees, then the angle is not a right angle" which is also a true statement. Example: a 37 degree angle is not a right angle.
Note: the original conditional "If P, then Q" would have the contrapositive be in the form "If not Q, then not P". We flip P and Q, and stick "not"s in front of both parts.
So this is why the answer is choice D
Answer:
B. 128 square centimeters
Step-by-step explanation:
So first make the top triangle part its own figure. By using information provided you can figure out the height of the triangle would be 3 by subtracting 11 from 14. Take 3 multiply it by the base and then 1/2 to get 18. Then find the area of the rectangle which would be 10 times 11 which is 110. Add the areas of the two parts, 110 and 18 to get 128.
It's simple really
12 can be devided into 3 equal groups of 4
Using the formula for the surface area of a box(cuboid) .
formula is
2(h*w)+2(h*l)+2(w*l)
here we will take the word used in the question "deep" to be its width..
→2(9*9) + 2(12*9) + 2(9*12)
=594cm²
