Answer:
15 minutes
Step-by-step explanation:
distance = rate · time
16 = 20r
r = 16/20 or 4/5 miles per minute
12 = 4/5·t
4t = 12·5
t = 60/4 or 15 minutes
2 kg. Each liter is equal to 1 kg
Step-by-step explanation:
Given that,
We have to find the value of m∠E.
Here, two sides are equal, thus it is an isosceles triangle. As the two sides are equal, so their angles must be equal. So, ∠E and ∠D will be equal. Let us assume the measures of both ∠E and ∠D as x.
→ Sum of all the interior angles of ∆ = 180°
→ ∠E + ∠D + ∠F = 180°
→ 116° + x + x = 180°
→ 2x = 180° – 116°
→ 2x = 64°
→ x = 64° ÷ 2
→<u> x = 32°</u>
Henceforth,
→ m∠E = x
→ m∠E = 32°
