Answer:
53.33
Step-by-step explanation:
finding area of ΔPAM
using similar triangles

16 = 12x; x = 
ΔPAM = 4/3 * 4 * 1/2 = 16/6 = 8/3
ΔPAL = 4 * 12 * 1/2 = 24
24 + 8/3 = 80/3 (using fraction form for now, will round later)
since there are two ΔPLM (ΔLMU has same area since they are congruent)
we can multiply 80/3 by 2
80/3 * 2 = 160/3 = 53.33
The side of the garden nearest tenth foot is - 9.5 feet
Given:Area of grandma's garden=90 square feet
To find:The length of the side nearest to tenth foot.
Solution:
Area=(side)^2
Side of the garden=√90
Therefore,√90=9.48683298
The sides of the garden are less than 10 feet but more than 9 feet
So,the side of the garden nearest tenth foot is -
9.5 feet
To solve for r, divide 2Pi to both sides of the equation. You will then get r=C/2Pi.
Answer:90 degree
Step-by-step explanation:
Measure its length.
Answer:
2sqrt3
Step-by-step explanation:
Since this seems to be a 45, 45, 90 triangle, x and y are the same.
The hypoteneuse is always the side lengths *sqrt2
We divide the hypoteneuse by sqrt 2 and get sqrt12
sqrt12 simplified is 2sqrt3
