I’m answering so the other peep can get brainliest she’s correct I think I’m pretty sure I think so thx for points have a great day byee
Step-by-step explanation:
Answer:
34
Step-by-step explanation:
x=3+√8
y =3-√8
now,
1/x^2+1/y^2
=1/(3+√8)² + 1/(3-√8)²
= [(3-√8)²+(3+√8)²] / (3+√8)²(3-√8)² [L.C.M = (3+√8)²(3-√8)² ]
=[(3-√8+3+√8)²-2(3-√8)(3+√8) ] / [(3+√8)(3-√8)]²
=[6²-2.(3²-√8² )] / (3²-√8²)² [ a²+ b²=(a+b)²-2ab]
=[36-2(9-8) ]/ (9-8)²
=[36-2.1] / 1²
=34
1092cm².
Answer:
Solution given:
First Side (a)= 18cm
Second side (b)=8cm
length(l)=15cm
height(h)=12cm
slant height (c and d)=13cm
Now we have
Total surface area of the trapezoid prism
=2 × area of base + lateral surface area
=2*area of trapezoid +perimeter of trapezoid*length =2*½*h*(a+b)+(a+b+c+d)*l
=12(18+8)+(18+8+13+13)*15
=1092 cm^2
Total surface area of the trapezoid prism is <u>1</u><u>0</u><u>9</u><u>2</u><u>c</u><u>m</u><u>²</u><u>.</u>
The calculator returns an error as the answer for the inverse sine of 1.055 because the acceptable range for sine is only from 0 to 1.00 in which 1.055 is clearly greater than. This is also the same as for the cosine values.
