Answer:
131 cm
Step-by-step explanation:
formula for surface area of pyramid is
S = (1/3)Bh
but the base ia a square, so B = 
S = (1/3)
the pic shows h = 8
but we don't know x
do SohCahToa
sin60 = x/8
x = 8sin60
x = 6.92820323 or 7
plug in numbers
S = (1/3)
8
S = 392/3
S = 130.6666667 or 131 cm
Answer:
The angles are supplementary.
Step-by-step explanation:
Angles that add up to 90° are complementary, while angles that add up to 180° are supplementary.
Answer:
y=2x-1
Step-by-step explanation:
straight line equation
y=mx + c
find gradient(m) first,use formula;
m=3-7/2-4
m= -4/-2
m=2
use one the coordinates
(2,3)
3=2(2)+c
3=4+c
c=3-4
c = -1
y = 2x - 1
Answer:
Step-by-step explanation:
3/12 and 2/9
LCM=36
3/12=9/36 AND 2/9= 8/36
9/36 IS GREATER
THEREFORE,3/12 IS GREATER
D. 150 should be your answer.
