Answer:
Number 1, (-2, -2)
Step-by-step explanation:
A circle measures 360°.
Since ∠DEF is equal to 70°, the rest of the circle will have a measure of 360 - 70 = 290°.
Central Angle and Arc relationship:
It states that the measure of the central angle and the arc that it intercepts are equal in measure.
Since ∠DEC is a central angle, its intercepted arc DF is also equal to 70°.
With this given facts, arc DGF is equal to 290°.
We can only solve for the degrees because radius is not given. Had it been given, the fraction 290°/360° will be multiplied to the circumference of the circle to get the length of the arc DGF.
its a simple 90 my friend please give me a brainleist

Step-by-step explanation:
Answer:
$ 63
Step-by-step explanation:
Let the new price ( price after the discount ) be x.
<u>Old price</u> <u>Discount</u> <u> New price</u>
100 30 70
90 30 x
<u>Now we can make an expression like this to solve this</u>
100 ⇒ 70
90 ⇒ x
<em>Use cross multiplication to solve for x.</em>
100x = 70 × 90
100x = 6300
<em>Divide both sides by 100.</em>
x =<u> $ 63</u>
