Answer:
angle CDE is 10 degree
Step-by-step explanation:
As angle C is 90
Angle E is equal to angle B which is 80 (180-100)
so 90+80+X=180
X=180-170
X=10
Complementary angles --- they add up to 90 degrees
Answer:
UHHH its 1/2

because it goes up 1 and run 2.
Answer:
C = 24.5 in
Step-by-step explanation:
Formula to find the circumference of a circle is :
C = 2πr
Here,
r ⇒ radius
So let us solve now.
C = 2πr
C = 2 × π × r
C = 2 × 3.14 × 3.9
C = 24.492 in
So, they've asked for nearest 10th.
Therefore, the answer will be 24.5 in.

Step-by-step explanation:
Given :-
The length of the garden 8m greater than 2 times the width.
Area of the garden is 280 m²
Let us consider the length as x and width as y.
Sp, we can day length as :-
x = 8 + 2y ---(1)
Now, we know that:-
Area of Rectangle = Length × Breadth
280 = x * y
We can replace the value of x now,
280 = y × ( 8 + 2y)
280 = 8y + 2y²
2y² + 8y - 280 = 0
y² + 4y - 140 = 0
Factorise it.
(y -10)(y + 14)
Cancelling -ve value, we get the width as 10 metres.
