Answer:
r = 
Step-by-step explanation:
The distance from the centre to a point on the circle is the radius r
Calculate r using the distance formula
r = 
with (x₁, y₁ ) = (0, 0 ) and (x₂, y₂ ) = (2, 5 )
r = 
= 
= 
= 
46/45. do u know how 2 do it? hope u do
Answer:
24,53cm²
Step-by-step explanation:
rectangle area=length×width=7×3
=21cm²
circle area=1/2Π r²
=1/2×3.14×1.5×1.5
=3.5325cm²
add the two areas
21+3.53=24,53cm²
Answer:
8+6=14
Step-by-step explanation:
that is my answer ig
Use the identity
sec^2x = 1 + tan^2 x
- so sec x = sqrt(1 + tan^2 x) then:-
tan x + sqrt( 1 + tan^2 x) = 1
sqrt ( 1 + tan^2 x) = 1 - tan x
1 + tan^2 x = 1 + tan^2x - 2 tan x
0 = -2 tanx
tan x = 0
x = 0, π
π is an extraneous root because sec 180 = -1
So the answer is 0 degrees
