Pythagoras' Theorem only works with right angle triangles.
A makes a right angles triangle because:
√3² + 4² = 5
However B doesn't because:
√7² + 8² = 10.631 (which is not 9)
Nor does C because:
√3² + 9² = √90 (which is not √95)
So the answer is A
Answer:
a) ∠BAC corresponds to ∠CDA
Step-by-step explanation:
We assume that the statement ∠BCA ≅ ∠CAD is supposed to mean ΔBCA ~ ΔCAD.
___
For any statement about correspondence to be true, the order of the vertex names in the statement must match the order of the vertex names in the similarity claim.
Here, the letters of ∠BAC are the 1st, 3rd, and 2nd letters of the name of the first triangle in the assumed similarity statement. The 1st, 3rd, and 2nd letters in the name of ΔCAD are C, D, A, so corresponding angles are ...
∠BAC and ∠CDA . . . . . matches answer choice A
_____
<em>Comment on the problem statement</em>
As written here, ∠C in the first triangle corresponds to ∠A in the second triangle. This tells you nothing about the relationships of the other angles or sides. That is why we have to assume a similarity statement is intended. Otherwise, the problem cannot be appropriately answered.

Answer:
hello dude
x - 9 = - 12
x = 9 -12
x = -3
HAVE A NİCE NİGHT
Step-by-step explanation:
Greetings from Turkey
Mary - M
<span>Jim - J </span>
<span>Mary's ticket number is one less than Jim's ticket number. </span>
<span>J - 1 = M </span>
<span>The product of their numbers is 812 </span>
<span>M * J = 812 </span>
<span>plus first equation into 2nd </span>
<span>(J - 1) J = 812 </span>
<span>J^2 - J - 812 = 0 </span>
<span>(J - 29) (J + 28) = 0 </span>
<span>J = 29 or -28, 29 cuz you can't have negative for question. </span>
<span>J = 29 </span>
<span>plus 29 in first equation, </span>
<span>29 - 1 = M </span>
<span>28 = M </span>
<span>Mary's ticket number is 28 and Jim is 29</span>
