Answer:
∠2 and ∠6
Step-by-step explanation:
Supplementary means that the angles added are a total of 180°.
∠5 and ∠8 are supplementary because they form a line, and a line is 180°.
∠1 and ∠2 are supplementary because they also form a line.
∠4 and ∠5 are supplementary because they are same side interior angles, and same side interior angles are always supplementary.
Only ∠2 and ∠6 are not supplementary because they are corresponding angles, and corresponding angles are congruent, not supplementary.
Answer:
18,223 feet
Step-by-step explanation:
y= -16t^2 + 608t + 12,447.
y = -16(t² - 38t) + 12447
y = -16[t² - 2(t)(19) + 19² - 19²] + 12447
y = -16(t - 19)² - 16(-19²) + 12447
y = -16(t - 19)² + 18223
Vertex: (19, 18223)
Max height is 18,223 at t = 19
Answer: it is 276
if i can be brainliest that would be great
10x7= 70 (Base 1)
10x7= 70 (Base 2)
10x4= 40 (Front)
10x4= 40 (Back)
7x4= 28 (Side 1)
7x4= 28 (Side 2)

SA= 276
