Answer:

      Q ' (3,4)

Step-by-step explanation:

When we reflect across the x axis, the y coordinate becomes -y

Q (3,-4) becomes Q' (3,- -4)

                              Q ' (3,4)

Please please help ASAP! Classify each angle!
Olenka [21]

Answer:

<h3>             Acute Angles: ∠TLS, ∠SLT, ∠ULR</h3><h3>             Right Angles:   ---------</h3><h3>             Obtuse Angles:  ∠RLT, ∠SLU, ∠ULS,</h3><h3>             Straight Angles:  ∠RLS, ∠TLU </h3><h3>             Not angles: ∠TRL </h3>

Step-by-step explanation:

The lines intersect at point L, so all angles have a vertex (middle letter) L so there is no angle TRL

Straight angle is a line with dot-vertex, so the straight angles are ∠RLS and ∠TLU.

∠TLS is less than 90° then it is acute angle (∠SLT is the same angle). ∠ULR is vertex angle to ∠TLS, so it's also acute angle.

Two angles adding to straight angle mean that they are both right angles or one is acute and the second is obtuse. ∠TLS is acute so ∠RLT is obtuse (they adding to ∠RLS) and ∠SLU is obtuse (they adding to ∠TLU). ∠ULS is the same angle as ∠SLU.

PLEASE HELP ME LIKE RN THIS IS 7TH GRADE MATH BTW
natulia [17]

Answer:

for the third one 2/5 for the fourth one 3/5

Step-by-step explanation:

For the first one, I put 10/25 as a fraction and found the least common multiple, which is 5. I then simplified, and got 2/5.

For the second one, I chose 3/5 because there are 3 friends whose names end in a, and 5 friends whose names do not end in a. My theory was that I took the friends and divided them into 2 groups by most common.

hope this helps if it doesn't I will correct myself :)
