Answer:
x = 20
Step-by-step explanation:
Here, we want to get the value of x
To get the value of x, we need to know the kind of relationship that exists between the two given angles
Both angles lie on a straight line and that means they are supplementary
What this mean is that they add up to 180
(5x-7) + (3x + 27) = 180
5x -7 + 3x + 27 = 180
5x + 3x -7 + 27 = 180
8x + 20 = 180
8x = 180-20
8x = 160
x = 160/8
x = 20
Since those lines are parallel, those two angles are equal. Therefore:
3x+15=105
3x=90
x=30
Answer:
m∠ABC = 130°
Step-by-step explanation:
BD is the angle bisector of angle ABC .
Therefore, ∠ABD ≅ ∠DBC
Measure of angle DBC = 65°
Therefore, m∠ABD = m∠DBC = 65°
m∠ABC = m∠ABD + m∠DBC
= 65° + 65°
= 130°
Answer: 10% were missing
Step-by-step explanation:
30 Students = 100% FYI in the problem
1/2 = 50%
50% + 40% = 90%
100% - 90% = 10%
Hope this helps.
