Answer:
x = 45°
Step-by-step explanation:
"Isosceles" means the base angles are congruent: they both have the same measure, 45°. (The hypotenuse is the "base" for this isosceles triangle.)
The acute angles of a right triangle are complementary, so the third angle can also be found as 90° -45° = 45°.
TRiangles ABE and ACD are similar because BE and CD are parallel.
Therefore CD / BE = AD / AE
8 / BE = 16 / 10
BE = 8*10 / 16 = 5
Also, 16 / 10 = AC / AB = 20 / AB
AB = 10 * 20 / 16 = 12,5
Perimeter of ABE = 5 + 10 + 12.5
= 27.5 units (answer)
Answer: 700 tons of coal consumed in 10 weeks.
Step-by-step explanation:
