Answer:
6=100°
8=80°
7=100°
9=80°
Step-by-step explanation:
If 6 is 100°
in a straight line theres 180 degrees
180-100=80°
8 is 80°
opposite 6 to 7 there are parallel corresponding angles meaning the angle opposite it will be the same. 8 with 9.
same with
Answer:
-19
Step-by-step explanation:
|19|=19
-1 * 19=-19
Equation~ 5b + (2b - 4) + (3b -6)= 180.
Answer:
∠4 and ∠3
∠4 and ∠5
∠3 and ∠6
Step-by-step explanation:
A pair of angles is said to be supplementary when the 2 angles add up to give 180°.
Two right angles add up to give 180°. Also, if we have two angles on a straight line, their sum = 180°, according to the linear pair property.
Thus, since m< 3 is given as 90°, m<4 = 90°.
m<4 + m<3 = 180°.
Therefore, <4 and <3 are supplementary.
<4 and <5, <3 and <6 are both linear pairs, therefore they are also supplementary.
