Ответ:
D
Step-by-step explanation:
It's an Icoseles triangle do the two bottom angles are equal. 50+ 50 = 100. All triangle angles add up to 180 so 180 - 100 = 80
Ответ:
Option D - 80
Step-by-step explanation:
The triangle is an isosceles triangle, which means that two angles and sides are the same. That means that other side is also 50°. All the angles in a triangle add up to 180°. Since we know two of the angles, we should know what the angle x is. We can write it as 50 °+ 50° + x = 180°. You can add 50° and 50° to get 100°. Now you have 100° + x = 180°. Subtract 100° from both sides to get x = 80°.
Hope this helps! :)

1)Only 60 of 500 colonists survived the period, now known as “the starving time.” Historians have never determined exactly why so many perished, although disease, famine (spurred by the worst drought in 800 years, as climate records indicate), and Indian attacks took their toll.
2)???
3)After the Indian Massacre of 1622 killed hundreds of settlers, the king revoked the Company's charter in 1624 and made Virginia a royal colony under his control.
