Answer:
<D = 100
<E =30
<F =50
Step-by-step explanation
Given that triangles triangle ABC and triangle DEF are similar, this means that their angles are congruent i.e
<A = <D
<B = <E
<C = <F
Given
<A = 100 then <D = 100
<B = 30°, then <E = 30°
To get <F, we will use the expression
<D+<E+<F = 180 (sum of angles in a triangle is 180°)
100+30+<F = 180
130+<F = 180
<F = 180-130
<F = 50°
Hence the measure of <F is 50°
Answer:
10m.
Step-by-step explanation:
Add up all the areas of the running path and then you can reach to the answer. I got 10m and most probably it should be that only.
3) Brett arrives 2 hours later than Lionel.
That is the correct answer.
(Sorry, I misinterprated the question before.)
