Answer:
the angle is not show but as known to me answer told by first guy is correct ☺
D=20in=lV2
l=20/V2=20V2/2=10V2
P=4*l
P=4*10V2
P=40V2
X*x*1.5x = 150
<span>1.5x³ = 150 </span>
<span>x³ = 100 </span>
<span>x = 4.641588834 </span>
<span>x ≈ 4.6 and y ≈ 6.9 <----- </span>
Answer:
Step-by-step explanation:
Remark
The diagonal is found by using the Pythagorean Theorem: a^2 + b^2 = c^2. This only works for certain figures. The rectangle is one of them.
Givens
a = 10
b = 8
c = ? This is the length of the diagonal.
Solution
a^2 + b^2 = c^2
10^2 + 8^ = c^2
100 + 64 = c^2
c^2 = 164
√c^2 = √164
c = 12.806
