Explanation:
Angles 1 & 2 have to equal 180. So, if ∠1 is equal to 140, ∠2 is equal to 40 because 140 + 40 = 180.
So far... we know that:
Angles 2, 9, and 11 make a triangle, a triangles "magic number" is also 180. To get 180, you must add up all of the angles. Well... we don't know ∠11 so to find it, you subtract 40 & 80 from 180. 180 - 80 - 40 = 60.
Answer:
∠2 = 40
∠11 = 60
8 * 6 = (4*6) + (4*6)
48 = 24 +24
48 = 48

The geometry illustrates that the value of DB is 34°
<h3>How to calculate the angles?</h3>
AB = 87°
ED = 37°
BCD will be:
= (360° - 87° - 32°)/2
= 118°
FA will be:
= 118°/2
= 59°
DC = 118/2 = 59°
HB = GA = 17°
DB = 2 × 17° = 34°
EG = GA = 17°

Answer:
<em>-120m+60</em>
Step-by-step explanation:
You have to distribute the -15 into the numbers in the 8m-4.
So, <u>-15 times 8m</u> plus <u>-15 times -4</u>
-15 times 8m is <u>-120</u>
-15 times -4 is <u>60</u>
Therefore, the answer is -120m+60
Their GCF would be equal to 12
