Csc(x) = 1/sin(x)
sec(x) = 1/cos(x)
cot(x) = [1/sin(x)] / [1/cos(x)]
cot(x) = 1/sin(x) * cos(x)/1
cot(x) = cos(x) / sin(x)
cot(x) = cot(x)
Answer:
y=25
2 of the y's = 50 in total
Step-by-step explanation:
180-115=x
x=65
180-90-65=y
y=25
Answer:
Step-by-step explanation:
a (2³)² = 2³ˣ² = 2⁶
b (7⁰)¹ = 7⁰ˣ¹ = 7⁰ = 1
c (5⁶)³ = 5⁶ˣ³ = 5¹⁸
d (6²)⁴ = 6²ˣ⁴ = 6⁸
e (8³)⁴ = 8³ˣ⁴ = 8¹²
f (4³)² = 4³ˣ² = 4⁶
g (9¹)² = 9¹ˣ² = 9² = 81
h (3⁷)² = 3⁷ˣ² = 3¹⁴
i (10²)³ = 10²ˣ³ = 10⁶
j (11²)⁴ = 11²ˣ⁴ = 11⁸
C. 224
10x8=80, 80/2=40, 40x4(all triangles)=160
8x8(square)=64
160+64=224
Answer:Area of wall =
ft
Explanation:First, we know that:1 in = 1/12 ft
Therefore, the dimensions of the wall would be as follows:H = 7 ft 10 in =
ft
B1 = 10 ft 2 in =
ft
B2 = 14 ft 1 in =
ft
For the trapezium, area can be calculated using the following the following formula:Area of trapezium = Average base * height =
* height
Substitute with the given to get the area as follows:Area of wall = ([
+
] / 2) *
Area of wall =
ft
Hope this helps :)
