Answer:
A. Show that the diagonals form two congruent triangles using the definition of a rhombus and geometric properties. Then, use CPCTC (corresponding parts of congruent triangles are congruent) to show that the opposite interior angles are bisected.
Step-by-step explanation:
Answer choice A is the only one that applies specifically to a rhombus.
The other answer choices are true of triangles and vertical angles in general. They do not relate specifically to the problem at hand.
Answer:
7
Step-by-step explanation:
Let the number be x.
-We then follow the rule of BODMAS to write the problem and solve for X:
Hence, the number is 7
Answer:
The answer is 5.4%
Step-by-step explanation:
30 of 18 is 5.4
-2,-35 just use the formula they give you
So, teh exact value is sqrt( 19^2 - 8^2 ) = sqrt( 361-64) = sqrt(297).
There's people who can calculate this mentally, but I can't. Approximate by known squares: 15^2 = 225, 16^2 = 256, 17^2= 289, 18^2=324,
So, 18.
