I really need help. Someone please help me with this.

9966 [12]

Answer:

angles 1, 3, 6, 8 = 142°

angles 2, 4, 5, 7 = 38°

Step-by-step explanation:

Vertical angles and corresponding angles are congruent, as are alternate interior angles. Hence the angles 1, 3, 6, 8 are all congruent:

∠1 = ∠3 = ∠6 = ∠8 = 142°

Each of the remaining angles forms a linear pair with one or another of those, so is its supplement:

∠2 = ∠4 = ∠5 = ∠7 = 180° -142° = 38°

Solve the radical equation. Be sure to check all solutions to eliminate extraneous solutions.

tatyana61 [14]

Answer: $\large\boxed{\text{No Solution}}$

Step-by-step explanation:

Given equation

$\sqrt{t+1}+9=7$

Subtract 9 on both sides

$\sqrt{t+1}+9-9=7-9$

$\sqrt{t+1}=-2$

Conclusion

$\text{Since radical values are always positive, it is false that }\sqrt{t+1}\text{ will equal to -2}$

$\text{Therefore, it is }{\large\boxed{\text{No Solution}}}\text{ in the context of real numbers}$

Hope this helps!! :)
