let's first convert this to number form.
3^6 / 3^3= what?
to divide a number with the same base but different exponent, we simply subtract the second exponent by the first exponent.
3^6 / 3^3 = 3^6-3=3^3
Remember, all the interior angles of a triangle equals 180.
So in triangle ABC, it already gives us two out of the three angles.
First, we add 52 and 36 and that gives us 88.
Now we subtract 88 from 180.
180 - 88 = 92
So that means that ∠ABC is 92°
Now we have to look at triangle DEF.
The equation says that triangle DEF is similar to triangle ABC.
Looking at the picture, triangle DEF is smaller and is flipped upside down.
So that means that ∠ABC ≈ ∠DEF
In similar triangles, the measurements of angles does NOT change. Just the side length.
So since ∠ABC = 92° that means that ∠DEF = 92°
Question 1:
48 + 63 + 28 + 44 + 43 = 226 minutes
41 + 40 + 15 + 1 + 39 = 136 seconds
136 seconds = 2 minutes and 16 seconds
The answer is 228 minutes and 16 seconds.
Question 2: 228 minutes = 3 hours and 48 minutes
The answer is 3 hours and 48 minutes, but if you're also counting seconds, add 16 seconds to the end of it.
Numbers shade ins and lines
I think the answer would be C. (btw, you should charge your phone/tablet, lol)
