Answer:
108
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 12 and d = 16 - 12 = 4, thus
= 12 + (24 × 4) = 12 + 96 = 108

Answer: 42 feet
Step-by-step explanation:
P-area of field
P=2100sqf
a-length of field
a=50 feet
P=a*b
2100sqf=50*b
b=2100/50
b=42 feet
Answer:
<em>22.62°</em>
Step-by-step explanation:
Considering △ABC. If angle B C A is a right angle, then;
m<BCA = 90 degrees
Given also
AB = 13
BC = 12
AC = 5.
According to SOH, CAH TOA;
Sin <B = AC/AB
Cos <B = BC/AB
Substitute the given values
Sin B = 5/13
B = arcsin(5/13)
B = 22.62
Cos B = 12/13
B = arccos (12/13)
B =22.62
<em>Hence the angles that make sinB = cosB is 22.62°</em>
