If two angles are equal, then they are both obtuse
Answer:
it 68.9
Step-by-step explanation:
because u add all that
Answer:
B.
Step-by-step explanation:
In statement (1), we are given that m∠BAC=m∠BCA
If the two angles are congruent, this means that the sides opposite the angles are also congruent. These sides are AB and BC. Therefore:
AB=BC | B. sides opposite equal angles are equal
:Done
*The side opposite a given angle is the side towards which the angle opens up to. For example, ∠BAC opens up towards the side BC, and ∠BCA opens up towards side BA.
Answer:
The answer to your question is:
16.- x = -6
17.- x = -4; x = 2
18.- x = -5
Step-by-step explanation:
16.- 
x + 6 = 0(x - 4)
x + 6 = 0
x = - 6
17.- 
(x + 4) (x - 2) = 0)(x + 6)
(x + 4)(x - 2) = 0
x + 4 = 0 x - 2 = 0
x = - 4 x = 2
18.- 
2x + 10 = 0(3x - 12)
2x + 10 = 0
2x = - 10
x = - 10/2
x = -5
