184 because 7+7is 14 and 14 +170 is 184
What I would do is subtract 12 from -5. Then you would have -17. Then you would add 4 and it would be -13. So your answer is:
<h2><em>
-13</em></h2>
Answer:
x = 99,53633682
Step-by-step explanation:
sin(34) = x/178
x = sin(34)×178
x = 99,53633682
Answer:
The answer is A, the measure of angle Z is 45°.
Step-by-step explanation: According to base angle theorem for iscoscles triangles, the base angles must be the same angle measure if the sides opposite to them are congruent. Since it is an iscoceles triangle, they are automatically congruent. This means that Y is 90 degrees. This fits into triangle sum theorem because if Z is 45 degrees, than x is also 45 degrees making a viable triangle. This means that this is the only one that actually applies. B is wrong because of triangle sum theorem, C is wrong because of triangle sum theorem, and D is wrong because of the SSS postulate and CPCTC.
