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.
340 you were right
Step-by-step explanation:
Answer:
she started with 50 marbles
Step-by-step explanation:
The total is 100 than you just subtract 20 and 30 becasue that is what is added later on. After you subtract 20 and 30 from 100 you will get 50. Therefore Sara had started out with 50 marbles.
