The artistic crop isn't helpful; it cuts off some vertex names.
The circumcenter H is the meet of the perpendicular bisectors of the sides, helpfully drawn. We have right triangle ELH, right angle L, so
EH² = HL² + EL²
EL = √(EH² - HL²) = √(5.06²-2.74²) ≈ 4.2539393507665339
Since HL is a perpendicular bisector of EF, we get congruent segments FL=EL.
Answer: 4.25
Answer:
187
Step-by-step explanation:
Least common multiple:
To find the required number,
- Find the LCM of 30 , 36 and 45
- Then add 7 to the LCM
30 = 2 * 3 * 5
36 = 2 * 2 * 3 * 3 = 2² * 3²
45 = 2 * 3 * 3 = 2 *3²
LCM = 2² * 3² * 5
= 4 * 9 * 5
= 180
Required number = 180 + 7
= 187
