ERGENT pls help The figure below shows a straight line AB intersected by another straight line t:

Write a paragraph to prove that the measure of angle 1 is equal to the measure of angle 3.

When two lines intersect they form two pairs of opposite angles, 1 + 3 and 2 + 4. Another word for opposite angles are vertical angles. Vertical angles are always congruent, which means that they are equal. Adjacent angles are angles that come out of the same vertex.

the answer is b i just did that

step-by-step explanation:

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
