Answer:
a) subtracting '8' on both sides, we get
- 5 x² + 8-8 = 133-8
- 5 x² = 125
b) The solution is x = 5 i
Step-by-step explanation:
<em>Explanation</em>:-
<u><em>Step (i):</em></u>-
Given quadratic equation - 5 x² + 8 = 133
subtracting '8' on both sides, we get
- 5 x² + 8-8 = 133-8
- 5 x² = 125
<u><em>Step(ii)</em></u>:-
dividing '-5' on both sides, we get

x² = -25

x = 5 i
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.
Answer:
x = 16
Step-by-step explanation:
First, find hypotenuse using 18 and 16.
Using Pythagorean theorem, it gives 24.08
now use it again with the hypotenuse and (36/2) = 18
This gives us x = 16
-6 + [4 - (x - 2)] = -6 + (4 - x + 2) = -6 + (6 - x) = -6 + 6 - x = -x
