Simple...
you have: 9u=10u-6
Isolate the variable-->>u
9u=10u-6
9u=10u-6
-10u -10u
-1u=-6
Now simply divide-->>
u=6
Thus, your answer.
Answer:
Correct choices are A and C
Step-by-step explanation:
Inscribed angles property: The inscribed angles subtended by the same arc are equal.
1. Angles EFH and EGH are both inscribed angles subtended by the arc EH. Therefore, these angles are congruent (option A is true).
2. Angles GHF and GEF are both inscribed angles subtended by the arc GF. Therefore, these angles are congruent (option C is true).
3. Angles EGH and FHG are interior angles of the triangle KGH and can be congruent (if triangle is isosceles) or can be not congruent (in general). Thus, option B is false.
4. Angles EFH and FHG in general are not congruent. They can be congruent only when arcs EH and FG have the same measure. In general, option D is false.
Answer:
three
Step-by-step explanation:
1) solving for roots
2) Quadratic formula
3) By completing square
We will use formula for circumference of circle:
lets name it as O
O = 2*r * pi
when we express r in this formula we get:
O = 2*2.2*pi
O = 4.4*pi
From this we can see that for given radius, answer is 4.4. The formula only depends on pi and that is what "in terms of pi" means.
Answer: m∠E = m∠C
m∠D = m∠B
Step-by-step explanation: When the triangle is rotated, the sizes and shapes of the angles remain the same. They just change positions. Match the shapes, the corresponding letters, and the measures of the angles will be equal.
It's like tipping over a chair. The legs are still the legs even if they are not still on the floor.
