Answer:
∠ EFG = 83°, ∠ GCE = 97°
Step-by-step explanation:
Since FE and FG are tangents to the circle then
∠ FGC and ∠ FEC are right angles
The sum of the angles in quadrilateral CEFG = 360°
Sum the 4 angles and equate to 360
3x + 11 + 90 + 5x - 23 + 90 = 360, that is
8x + 168 = 360 ( subtract 168 from both sides )
8x = 192 ( divide both sides by 8 )
x = 24
Thus
∠ EFG = 3x + 11 = 3(24) + 11 = 72 + 11 = 83°
∠ GCE = 5x - 23 = 5(24) - 23 = 120 - 23 = 97°
Answer is 50
Reason
Using Pythagorean theory
a^2 + b^2 = c^2
a and b are the legs, the hypotenuse is c
14^2 + 48^2 = c^2
2500 = c^2
Now take the square root of both sides
50 = c
The volume of any rectangle is
length x width x height = cubic units
Convert fractions to decimals (easier to multiply with) and solve
Label the units as: cubic feet, cubic inches, etc
1) 6 x 3.33 x 1.66 2) 2.25 x 3 x 2.25 3) 15 x ? x ?
4) 10 x 3.5 x 1.5 5) 4 x 1.75 x 2.5 6) 5.25 x 3.75 x 2
Hope this helps.
