Answer:
- x = 30°
- DB = 26
- AD = BC = AB = DC = 7
Step-by-step explanation:
- <em>Diagonals of a square are congruent and perpendicular and bisect each other</em>
<h3>Q4</h3>
m∠AEB = 3x
m∠AEB = 90°
<h3>Q5</h3>
AE = 3x - 2
EC = 2x + 3
- AE = EC
- 3x - 2 = 2x + 3
- 3x - 2x = 3 + 2
- x = 5
DB = EC = 2(AE) = 2(3*5 - 2) = 2(13) = 26
<h3>Q6</h3>
<u>AD and BC are the sides, which are equal</u>
- 2x - 1 = 5x - 13
- 5x - 2x = 13 - 1
- 3x = 12
- x = 4
AD = BC = AB = DC = 2*4 - 1 = 7
5(3x)+4=-10 i think that is the correct answer
Essentially, what you need to do is ensure that both sides cancel each other out to make 0 = 0
An example:
2(x + y) + 4 = (4x + 4y + 8)/2
2x + 2y + 4 = 2x + 2y + 4
0 = 0
Answer:
21
Step-by-step explanation:
you first look at the circle
next you see the numbers in the circle
after that you multiply the numbers together
so, 3 x 7 = 21
All of these angles can be compared to each other.
There are:
- Alternate interior angles
-- Angles that share one line and two parallel lines and are less than 90 degrees (angles 10, 12). These angles are equal to each other.
- Alternate exterior angles
-- Angles that share one line and two parallel lines and are more than 90 degrees (angles 1,5) These angles are equal to each other.
- Vertical Angle
-- Angles that share a point and are opposite of that point (angles 2,3) These angles are equal to each other.
-Supplementary angles
-- Angles that are on the same side of one line and share the side of another (angles 9,10). These angles are always equal to 180 degrees.
Using this we know:
a. m of angle 5 = to the m of angle 3 = 102
m of angle 5 = 102 degrees
