Can someone help me with this question.

Mathematics
1 answer:
Flauer [41]3 years ago
5 0

Explanation:

angle BCA ≅ angle ECD . . . . . . vertical angles are congruent

∆BCA ≅ ∆ECD . . . . . . . . . . . . . . SAS congruence theorem

BA ≅ ED . . . . . . . . . . . . . . . . . . . .CPCTC

__

Based on the given congruences and the congruence of the vertical angles at C, we can invoke SAS congruence to show ∆BCA ≅ ∆ECD. Then the desired segments are congruent because corresponding parts of congruent triangles are congruent.

3x+7y=-6 -7x+3y=26 -4x+4y=-32 +4x on both sides and you end up with 4y=-32+4x now divide both sides by 4 and you get y=-8+x then to incorporate that in one of the problems 3x+7(-8+x)=-6 do the distributive property with the 7 into the () and you get 3x-56+7x=-6 now add all common variables and get 10x-56=-6 now add 56 to both sides and you get 10x=50 now divide by 10 on both side and you get x=5 now for getting y to equal a number instead of an equation 3(5)+7y=-6 15+7y=-6 subtract 15 on both sides to get 7y=-21 not divide by 7 on both sides to get y=-3 your answers are y=-3 and x=5

Can you help me with this question?
Troyanec [42]
Assuming you are focusing on the square only, then the answer is 9 inches.

You take the square root of 81 to get 9. Notice how 9^2 = 9*9 = 81. So if you're not familiar with square roots, then think backwards in a sense to get the answer.
