Answer:
172.27 in
Step-by-step explanation:
Apply the Sine Rule
Sine Rule is given as:
c = x = ?
C = 180 - (52 + 48) = 80° (sum of triangle)
b = 130 in.
B = 48°
Plug in the values
Multiply both sides by sin(80)
172.274641 = x
x = 172.27 in. (to 2 decimal places)
1. 10x8 =80cm
2. 2.5 x 4.33=10.825ft triangles is base x height so it is half of 5 which is 2.5 to get the base number
3. 11x13= 143 ft
4. 8.5x12=102m
7. 12x 6 =72cm
8. (10x3)1/2=
30x1/2= 15in
Answer:
22cm²
Step-by-step explanation:
radius of smaller circle= 7/2=3.5cm
area of smaller circle=π×3.5=11cm²
area of bigger circle=π×10.5(radius is 7 plus 3.5)=33cm²
area of shaded area=33-11=22cm²
