Hey!
------------------------------------------------
Surface Area Formula: 2LW * 2LH * 2WH
------------------------------------------------
2LW:
5 x 1 = 5
5 x 2 = 10
------------------------------------------------
2LH:
4 x 1 = 4
4 x 2 = 8
------------------------------------------------
2WH:
5 x 4 = 20
20 x 2 = 40
------------------------------------------------
Surface Area:
40 + 8 + 10= 58
------------------------------------------------
Answer:
D) 58 cm2
------------------------------------------------
Hope This Helped! Good Luck!
(-3)^2 = 9
-3^2 = -9
Hope this helps!
Answer:
B
Step-by-step explanation:
Since the triangle is right use the sine/ tangent ratios to solve for x and y
note sin60° = 
and tan60° = 
sin60° = 
= 
ysin60° = 3
y × = 3
multiply both sides by 2 and divide by
y v= 6
= 6
tan60° = 
= 
xtan60° = 3
x × = 3
divide both sides by
x = 3 = 3
