Please help with this ASAP!!1
d1i1m1o1n [39]

Answer:

a. OM is congruent to ON.

Step-by-step explanation:

To use the HL Theorem, you must have a congruent hypotenuse and a congruent leg. In this case, you have two congruent hypotenuses. You just need to find two congruent legs.

a. OM is congruent to ON. This says that two legs are congruent, so this is your answer.

b. LM is congruent to ML. This does not help as it is saying a segment is the same as the same segment.

c. and d. Both of these use angle measurements, which does not help with the HL Theorem.

Hope this helps!

Mairisa gets $8 per week for an allowance. She saves 25% of her allowance each week. How long will it take Mauritania to save $1
Leona [35]

8 weeks

First, find how much money Maurisa saves each week. 25% is the same as 1/4, and 1/4 of 8 is 2, so Maurisa saves $2 each week.

Finally, just divide $16 by $2 per week to find that Maurisa will take 8 weeks to save $16.
