Answer:
391.2cm²
Step-by-step explanation:
Triangle = 1/2bh*2=1/2(4)(6.9)(2)=27.6 for each end triangle.
14*8=112 for each rectangular side.
112+112+112+27.6+27.6=391.2cm²
Answer:
13.4 inches
Step-by-step explanation:
Firstly you should calculate the diagonal of lower square using pythahoras theorem
I.e diagonal = (89)^1/2
Now calculate distance by simple arithmetic
X=Xx + Xy
= (89)^1/2 + 4
= 13.4
Step-by-step explanation:
Firstly, we'll try to simplify the integrand. By hint 1, we see that:
Simplifying the integrand gives us:
Next, by hint 2, we observe that:
So this tells us to make the substitution: 
Doing so gives us:
, which should be trivial.
Answer:
62°
Step-by-step explanation:
In an isosceles triangle, angle opposite to equal sides are equal.
So according to angle sum property :
x + x + 56 = 180
2x + 56 = 180
x = 180 - 56 /2
x = 62°
Answer:
2x-5=4
2x=9
x=9/2=4.5
or
2x-5=-4
2x=1
x=1/2
