Answer:
D) 20°
Step-by-step explanation:
Using the triangle sum theorem, you know that every triangle's interior angles add up to 180°. Therefore the bottom triangle's missing angle can be found by giving it the variable x.
57° + 30° + x = 180°
Simplify: 87° + x =180°
x=93°
By the vertical angles theorem, the vertical angle directly across this angle is congruent to this one. Meaning that the top triangle's angle are 67°, 93°, and unknown, which we can assign y. We can use the same method from above here.
67° + 93° + y = 180°
Simplify: 160° + y = 180°
y=20°
Estimation :
20/0.05 = 400
Answer:
80
Step-by-step explanation:
we search for a square number so that rows*plantsInARow gives us the number
The number should be around 50², guessed
50² = 2500 (to low)
51² = 2601 (still to low)
52² = 2704 (bingo)
now to get from 2624 to 2704 plants he needs 80 more. That is the least number.
He could also go to plant 60² plants an than need slot more.
(would really appreciate the brainliest)
16 and 1/5 is equal to 16.2
So 19.8 subtract 16.2 is equal to 3.6
Savannah is 3.6 or 3 and 3/5 seconds faster than Paloma.
