Answer:
10+^@=72_^) + the series
Step-by-step explanation:
Answer:3.294. Hope this helps!
Step-by-step explanation:
This is the concept of trigonometry, to get the possible length of side a we use the sine rule which states that:
a/sin A=b/sin B=c/sin B
where;
a,b and c are the sides
A,B and C are the angles
thus the value of A could be as follows;
assuming the triangle is an isosceles triangle, the base angles will be:
(180-40)/2=70
thus;
15/sin 70=a/sin 40
a=(15sin40)/sin70
a=10.26 inches
thus the possible size of a=10.26 inches
The series would be look like this with adding the next number
<span>1,49,1625,3649,6481
</span>The key to get this number is<span> concatenate two consecutive squares together for each term.</span>
<span>The total surface area is SA = 6 </span>×
;
SA = 6 ×
= 6 × 81 = 486
