AB = 7 1/2

BC = 2 1/4

DE = 1 1/4

AB = GH + EF + CD

AH + FG = DE + BC

The perimeter is AB + BC + CD + DE + EF + FG + GH + HA.

AB + BC + CD + DE + EF + FG + GH + HA =

= AB + BC + DE + AB + DE + BC =

= 2AB +2BC +2DE =

= 2 · 7 1/2 + 2 · 2 1/4 + 2 · 1 1/4 =

= 15 + 4 2/4 + 2 2/4 =

= 15 + 4 1/2 + 2 1/2 =

= 19 1/2 + 2 1/2 =

= 22 [m]

Please answer !!!!!! Will mark brainliest !!!!!!!!
Inga [223]

Answer:

f(u) = 9/5

Step-by-step explanation:

u - 5 = -4(u - 1)      Distribute on the right side

u - 5 = -4u + 4

+4u      +4u            Add 4u to both sides

5u - 5 = 4

    + 5   + 5            Add 5 to both sides

5u = 9                    Divide both sides by 5

u = 9/5

ABC is a tangent to the circle below. O is the centre of the circle. Work out the size of angle 0. Give reasoning to justify you
Delvig [45]

Answer:

Θ = 46°

Step-by-step explanation:

the angle between a tangent and a radius at the point of contact is 90° , so

∠ ABO = 90°

since OB = OD ( radii of circle ) then Δ BOD is isosceles and

∠ OBD = ∠ ODB = 22°

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ AOB is an exterior angle of the triangle , then

∠ AOB = 22° + 22° = 44°

the sum of the 3 angles in Δ AOB = 180° , then

Θ + 44° + 90° = 180°

Θ + 134° = 180° ( subtract 134° from both sides )

Θ = 46°
