Answer:
∠1 = ∠3 = ∠5 = ∠7 = 81°
∠2 = ∠4 = ∠6 = 99°
Step-by-step explanation:
Vertical and corresponding angles are congruent. Angles 1 and 99° are supplementary, so ...
∠1 = 180° -99° = 81°
Then we have ...
∠1 = ∠3 = ∠5 = ∠7 = 81°
∠2 = ∠4 = ∠6 = 99°
Answer:
23
Step-by-step explanation:
100 is the exterior angle.
( 2x + 3 ) and 51 are interior angles.
Formula : -
Exterior angles = Sum of two interior angles.
100 = 2x + 3 + 51
100 = 2x + 54
2x = 100 - 54
2x = 46
x = 46 / 2
x = 23
6(1/2 + 2/3 + 3/4)
= 6(1/2) + 6(2/3) + 6(3/4)
= 3 + 4 + 4 1/2
= 11 1/2
Answer
11 1/2 (23/2 or 11.5)
Step-by-step explanation:
Given
25 - (- 4)
= 25 + 4
= 29
Hope it will help :)
