perimeter ≈ 18.9 units ( to 1 dec. place )
Calculate the lengths of the 3 sides using the distance formula
d = √( (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = A(1, 1) and (x₂, y₂ ) = B(9, 2 )
d = √( (9 - 1 )² + (2 - 1 )² ) = √(64 + 1 ) = √65
repeat with (x₁, y₁ ) = B(9, 2) and (x₂, y₂ ) = C(4,5 )
d = √( (4 - 9 )² + (5 - 2 )² ) = √(25 + 9 ) = √34
let (x₁, y₁ ) = A(1, 1 ) and (x₂, y₂ ) = C(4, 5 )
d = √( (4 - 1 )² + (5 - 1 )² ) = √(9 + 16 = √25 = 5
perimeter = √65 + √34 + 5 ≈ 18.9 units
Answer:
c
Step-by-step explanation:
Answer:
41°
Step-by-step explanation:
Supplementary angles are angles that has their sum total of angles as 180°.
If two angles ∠x and ∠ y are supplementary, this means
∠x+∠y = 180° ... (1)
Since ∠y = 139°, to get ∠x, we will substitute the value of ∠y in equation 1 to have;
∠x + 139° = 180°
∠x = 180°-139°
∠x = 41°
Therefore the measure of ∠x is 41°
Answer:
fg(x) = 32x²+44x+16
Step-by-step explanation:
fg(x) = f[g(x)]
= f(4x+3)
= 2(4x+3)²-(4x+3)+1
= 2(4x+3)²-(4x+3)+1
= 2(16x²+24x+9)-4x-3+1
= 32x²+44x+16
210 because if you multiply 10 by 35 to get 350 you have to multiply 6 by 35 then you get 210
