Given: 7r+3r-8=8+2r
Simplify: 10r-8=8+2r
Addition: add 8 to each side: 10r=16+2r
Subtraction: Take 2r from each side: 8r=16
Division: Divide each side by 8 for answer: r=2
Answer: r=2
Answer:
8.2 units
Step-by-step explanation:
Given that the only information for our triangle are 2 sides and 1 angle, we must use the Law of Cosines to find side BC
<u />
<u>Recall the Law of Cosines</u>
<u />
<u>Identify angles and sides</u>
<u />
<u>Solve for side "a"</u>
<u />
Therefore, the length of line segment BC is about 8.2 units
Answer:
The Correct Answer is 30 if your finding the Area of the triangle prism
Step-by-step explanation:
A is not a subset of B but B is a subset of A (that is can be found in A) that is B⊆A is correct
<h3>Set theory</h3>
Set is defined as the arrangement of elements. They can be represented using the venn diagram.
Given the following sets
U = {x: x is an integer and 2≤x≤10} = {3, 4, 5, 6, 7, 8, 9}
A = {x: 2x+1>7} = {x > 3}
B={x: x^2>20} = {x >± 20}
From the set, can see that A is not a subset of B but B is a subset of A (that is can be found in A) that is B⊆A is correct

Answer:
180°
Step-by-step explanation:
∠LMN = 90° and is the angle in a semicircle, thus
LN is the diameter of the circle and the measure of arc LPN is
m arc LPN = 180°
