Answer:
lateral surface area of a pyramid= 1/2pl or pl/2
Answer:
55°
Step-by-step explanation:
Angles x and 125° are linear pair,
So,
x + 125° = 180°
x = ( 180 - 125 )°
x = 55°
If we say that side "a" is the shortest (adjacent), side "b" is the second shortest (opposite), and side "c" is the longest (hypotenuse): then angle A would be 30°, angle B would be 60°, and angle C would be 90°
tan B = b/a
or
a tan B = b
they have 4 as the smallest value in all four options, so we know that
a=44 tan 60° = b
tan 60° = √3
so, 4 tan 60° = 4√3
b=4√3that leaves two options left, so now we find "c":
c^2 = (a^2) + (b^2)
OR



so
a=4, b=4√3, and c=8
Making your answer
B
Answer:
B
Step-by-step explanation:
The circumference (C) of a circle is calculated as
C = 2πr ( isolate r by dividing both sides by 2π )
C ÷ 2π = r → B
