Answer:
2° = 7° is true
Step-by-step explanation:
Since line c is not parallel to line a and b:
- 9°,10°,11° and 12° cannot equal to 1°,2°,3°,4°,5°,6°,7° and 8°.
Because line c is not parallel, 9,10,11 and 12 gives different measure.
So 7° = 10° is false because like said, these angles give different measure and 7° cannot equal to 10° since both lines are not parallel. Alternate Interior Theorem does not work because both lines are given not parallel.
2° = 7° is true because both lines are parallel and we can use Alternate Exterior Theorem
Or since 2° = 6° and 6° = 7° because cross-intersect forms same measureof opposite sides. Hence, 2° = 7°
8° = 9° is false and the reason is same as 7°=10°.
Answer:
0i + 10j, or just 10j
Step-by-step explanation:
Vector u = <6, -4> and vector v = <12, 2>.
We are to find v - 2u, which is:
<12, 2> - 2<6, -4>. We combine x components and y components to obtain:
<12-12, 2+8>, or <0, 10>.
In terms of i and j, that'd be 0i + 10j, or just 10j.
Answer:
angle P = 130 degrees
arc SF = 50 degrees
Step-by-step explanation:
angle P = 130 degrees because it is alternate adjacent to 130 degrees.
130 = 1/2(210+SF)
130 = 105+1/2SF
1/2SF = 25
arc SF = 50 degrees
12r−8−12
=12r+−8+−12
Combine Like Terms:
=12r+−8+−12
=(12r)+(−8+−12)
=12r−20
Answer:25
