The complete exercise is attached.</h3>
For this exercise it is important to remember that, by definition, if an angle formed by two intersecting chords has its vertex on a circle, this is called an "Inscribed angle".
The following formula is used to calculate the measure of an Inscribed angle:
You can identify in the figure that:
Then you can substitute values into the formula and solve for "x":
Then, AC is:
B. 2 1/5
Divide the 11 cakes by the 5 people.
11/5 =2.2
To convert 2.2 to a fraction:
Put 2.2 over one:
2.2/1
Then multiply both the numerator and denominator by the number of places after the decimal. Since we move by one place, we multiply both by 10.
2.2*10/1*10 = 22/10
Reduce the fraction.
22/10=11/5
Now divide the 11 by the five. 5 can fit into 11 two times, with 1/5 left over.
Step-by-step explanation:
step 1. KITE is a kite
step 2. <ski + <kis + 90 = 180 (internal angles of a triangle has a sum of 180)
step 3. <ski + 25 = 90
step 4. <ski = 65°
step 5. <kes = <kis (angles across equal sides are equal)
step 6. <kes = 25°
step 7. <kie = <kis (they are the same angle)
step 8. <kie = 25°.
step 9. let's call ek = x and et = 1 5x
step 10. therefore x + 1.5x + x + 1.5x = 55
step 11. 5x = 55 or x = 11 = ek
step 12. et = 1.5x = 1.5(11) = 16.5.
The answer would be A. because 30 is how many she did but then h is the variable we are trying to figure out like the h can be any letter it just is there to show that the "person" does not know what the number is. Hope this helped!
