Given two similar triangles
So, the corresponding angles are congruent, and the corresponding sides are proportional
As shown:
m∠ Y = 35, m∠ X = 90
So, m∠ W = 90 - 35 = 55
And the triangle XYW is similar to the triangle ECD
So,
5.88 / 3 = 1.96 per pound
original price - 1.21 per pound
Answer:
x < - 3
Step-by-step explanation:
F = kq2 / r2
q = ne
F = k(ne)2 / r2
n = âš(r2F / ke2) = (r/e) âš(F/k)
k = 9 x 109 Nm2/C2
e = 1.6 x 10-19 C
n = [(4.2 x 10-10) / (1.6 x 10-19)] âš[(5.2 x 10-9) / (9 x 109)] ≅ 1.995 ≅ 2
Answer:
Step 1
Step-by-step explanation:
they were supposed to multiply 2x by 4 and -1 by 4 but they only multiplied 2x by 4.
