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:
5808.8km
Step-by-step explanation:
Answer:
37 inches.
Step-by-step explanation:
Well, we know the formula is a²+b²=c²
So, first plug in leg one and leg two:
12²+35²=c²
Now, solve.
144+1225=c²
1369=c²
Okay, so we have to square root 1369 to find c.
The square root of 1369 is 37.
Therefore, the answer is 37 inches.
Answer:
Side length = 8xy^2
Perimeter = 32xy^2.
Step-by-step explanation:
As it's a square the side length is the square root of the area
= √ (64x^2y^4)
= 8xy^2.
The perimeter is 4 times this.
Answer:
That's the mathematical meaning of equation, but equation can also be used in any number of situations, challenges, or efforts to solve a problem. The "equa" at the beginning of equation will be familiar from other words such as "equal," "equality," and "equate."
