All you have to do is go to the location of the number and go over the other location of the other number
Answer:
6. r = 21 cm
7. A = 155.5 m²
Step-by-step explanation:
7: Formula for arc length is;
S = (θ/360) × 2πr
We are given;
S = 51 cm
θ = 139°
Thus;
51 = (139/360) × 2π × r
Making r the subject;
r = (51 × 360)/(2π × 139)
r ≈ 21 cm
8) Area of sector is gotten from the formula;
A = (θ/360) × πr²
A = (220/360) × (π × 9²)
A = 155.5 m²
Answer:

pls can i have brainliest
Answer:
Infinitely many
Step-by-step explanation:
12x+1=3(4x+1)-2
Expand 3(4x+1)-2
12x+3-2
12x+1
12x+1=12x+1
Simplify.
0=0
True for all values of x
Answer:
missing angle = 70 degrees
Step-by-step explanation:
180 -120 =60, because supplemenatery angles add up to 180 degrees.
sum of all angles of a triangle = 180. so 180-60-50=70 degrees
