Answer:
- 6 x - 182
Step-by-step explanation:
It'll be an acute angle, because a right angle would've been 90° but it's 89°. An obtuse angle would've been over 90°.
Answer:
D. 160
Step-by-step explanation:
The sum of the sequence 1, 2, 3, 4, ... , n is n(n + 1)/2.
Here, you have the sum of 4(1, 2, 3, 4, ... , n), so the sum is 4[n(n + 1)/2]
In this case, the first term is 0, so the last term is the 8th term of the sequence above, so n = 8
4[n(n + 1)/2)] =
= 4[8(9)/2]
= 4[72/2]
= 4(36)
= 144
The closest answer is D. 160
Answer: a) similar, SSS similarity
<u>Step-by-step explanation:</u>
ΔLSR sides <em>in order from least to greatest</em> are: 24, 33, 36
ΔLNM sides <em>in order from least to greatest</em> are: 112, 154, 168
If the triangles are similar then their corresponding sides will be proportional
Their corresponding sides are proportional so
ΔLSR ≅ ΔLNM by Side-Side-Side Similarity Theorem
