0. 24's opposite is -24. 24 more than -24 is 0.
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:
B
Step-by-step explanation:
At the numerator we have to put 8, while at the denominator we have to put 26
8/26
now we can simplify the fraction by dividing both numerator and denominator by 2
(8:2)/(26:2)
4/13
Answer:
y= 40x+20
Step-by-step explanation:
Answer:
16.64645cm²
Step-by-step explanation:
All of the angles are equal: A = B = C = 180/3 = 60°.
All of the sides are equal: a = b = c.
h = 5 cm, sin60 = h/a = 5/a, a = 5/sin60 = 5.77 cm.
Area = 1/2bh = 1/2 x 5.77 x 5.77 = 33.2929/2 = 16.64645cm²
