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.

Using Pythagorean, a^2 + b^2 = c^2
16 +x^2 = 36.69
Then subtract the 16 from 36.69, which is 23.69
And finally take the square root of that, giving you 4.87

Given a sequence is defined by a first term of LaTeX: t_1=3t 1 = 3, and explicit definition LaTeX: t_n=\:4n-1t n = 4 n − 1, find

Debora [2.8K]

Answer:

$1) 15\: 2)(-4,-1,11,20,...)$

Step-by-step explanation:

1) To find the 4th term given the Explicit Formula, i.e. definition, just plug it in. The common difference according to question is 4, the 1st term is 3.

$t_{1}=3\\t_{n}=t_{1}+4(n-1)\\t_{n}=t_{1}+(n-1)d\\t_{4}=3+4(3)\\t_{4}=15$

2) For this another Sequence in Explicit definition we just need to plug it in:

$a_{n}=n^{2}-5\\a_{1}=1^{2}-5 \Rightarrow a_{1}=-4\\a_{2}=2^{2}-5\Rightarrow a_{2}=-1\\a_{3}=3^{2}-5\Rightarrow a_{3}=4\\a_{4}=4^{2}-5\Rightarrow a_{4}=11\\a_{5}=5^{2}-5\Rightarrow a_{5}=20\\(-4,-1,11,20,...)$

Ana’s gymnastics scores were posted on the scoreboard in order from highest to lowest score. One digit in her floor score is not

aalyn [17]

Answers :a) digits are 1, 2, 3, 4 , b) difference is 0.367

Step-by-step explanation:

The floor score must be higher than 15.133 and lower than 15.500

The missing digit must be an integer.

Then all the possible scores are: 15.166 , 15.266 , 15.366 and 15.466

Because 15.166 > 15.133 and 15.466 < 15.500

Then all the possible digits are 1 , 2 , 3 , 4

The difference between her vault score and her uneven bar score is

15.500 - 15.133 = 0.367

Answers :a) digits are 1, 2, 3, 4 , b) difference is 0.367
