Answer:
80 degrees
Step-by-step explanation:
ALL TRIANGLES MUST EQUAL 180 DEGREES!
180-70-30 = 80
Say it with me.
<em>ALL TRIANGLES MUST EQUAL 180 DEGREES!</em>
<em>ALL TRIANGLES MUST EQUAL 180 DEGREES!</em>
<em>ALL TRIANGLES MUST EQUAL 180 DEGREES!</em>
Also, triangle CED reflects over the invisible y-axis. Angle C is shared = 70. Angle E is Angle A, and Angle B is Angle D (which is 80 degrees).
Answer:35N
Step-by-step explanation:
Cross multiply and divide to find the missing value
Answer:
9 in.
Step-by-step explanation:
Given that the 4 in and 10 in. lines are parallel, the two triangles are similar.
As such, the ratio of the sides would give the same results.
Hence,
4/6 = 10/(6 + x)
cross multiplying
4(6 + x) = 60
Dividing both sides by 4
6 + x = 15
collecting like terms
x = 15 - 6
= 9
Dot product is
a*b = |a|*|b|*cosα.
In our case
u*u =|u|*|u|*cos 0
u*u =|u|*|u|
12=|u|²
|u|=√12=√(4*3)=2√3
Answer: <span>D. 2√3</span>
Which of the following sets represent A ∪ B? {6, 12} {2, 3, 4, 6, 8, 9, 10, 12} {1, 5, 7, 11} {2, 3, 4, 8, 9, 10}

<h3>AUB = { 2, 3, 4, 6, 8, 9, 10, 12}</h3>
<em><u>Solution:</u></em>
The complete figure of question is attached below
From figure,
Write all elements from set A
A = {3, 6, 9, 12}
Write all elements from set B
B = {2, 4, 6, 8, 10, 12}
AUB means A union B
AUB means set of all the numbers combined with set A and set B
Combine set A and B
AUB = { 2, 3, 4, 6, 8, 9, 10, 12}
Thus AUB is found
