Answer: see below
Step-by-step explanation:
Presuming you meant this
0< θ < 90 degree; tan (θ) = 7/8 find cos (θ)
Using the identity
1 + tan²θ = sec²θ (where sec θ = 1/cosθ)
cosθ = √{1/(1 + tan²θ)} = √{ 1/(1 + (7/8)²} = √{ 1/(1 + 49/64)}
= √{ 64/113} = 8/√113 <= answer.

or Not Congruent
Answer:
SSS
Step-by-step explanation:
The sides of ABC and DEF are equal
AC = DF
CB = EF
AB = DE
Because the sides of both triangles correspond, the two are congruent
Answer:
SSS
Step-by-step explanation:
The sides on the triangles are of the same length.
AC = CF
CB = EF
AB = DE
Answer:
20 m/s
Step-by-step explanation:
Distance = rate * time
400 m = rate * 20 seconds
Divide each side by 20 seconds
400m/ 20 seconds = rate
20 m/second = rate

Answer: 1/18
Step-by-step explanation: The x's basically cancel each other out so all that is left is the 1 and the 18
Answer:
The length is 10 yards and the width is 20 yards of the playground.
Step-by-step explanation:
Given,
Area of the rectangular playground = 200 yards.
Solution,
Let the length of the playground be x.
Then the width of the playground is 2x.
Now, According to the formula of area of rectangle;
On substituting the values, we get;
So the length of the playground is 10 yards.
Since the width is twice of the length.
So width =
Hence the length is 10 yards and the width is 20 yards of the playground.
