Minor Arc AC = 110 degrees (given)
As indicated in the hints,
OA=OC => OAC=OCA=(180-110)/2 = 35
Similarly,
OAB=OBA=(48-35)=13
=>
OBC=OCB=(180-35-35-13-13)/2=(180-96)/2=84/2=42
=>
Angle B = 13+42 = 55 degrees

Check:
55+55+35+35+13+13 = 180 degrees (angles of a triangle) ok.

Write an equation of the line that is parallel to y=1/2x+3 and passes through the point (10,-5)

Brut [27]

Answer:

13

Step-by-step explanation:

x y

y=1/2x+3 and passes through the point (10,-5) 10 = x and -5 =y 1/2(10) - this mean times

-5 = 1/2(10) +3

1/2(10/1) = 1 x 10 and 2 x 1 = 10/2 = 5

-5 = 5 + 3 = 7

-5 = 7 + 5 + 7

+5 +5

= 13

What is the approximate area of the shaded sector in the circle shown below

harina [27]

Answer:

Option A. 283 cm²

Step-by-step explanation:

to find the area of the shaded sector, we use the formula:

$\frac{\text{angle given}}{360^\circ}\times \text{area of the circle}$

where area of the circle = πr²

∴ for the given circle,

$\text{Area of the sector}=\frac{\text{given angle}}{360^\circ} \times \pi r^2$

= $\frac{100}{360}\times 3.14\times 18\times 18$

= $\frac{100}{360}\times 1017.36$

= 282.6

≈ 283 cm²

The approximate area of the shaded sector is 283 cm².
