Answer:
x = 16
Step-by-step explanation:
Since ∆ABC is congruent to ∆DEC, their corresponding angles would be equal to each other.
<B is congruent to <E, therefore,
<B = <E
x + 15 = 6x - 65 (substitution)
Collect like terms
x - 6x = -15 - 65
-5x = -80
Divide both sides by -5
x = 16
Answer:
76.9690 square units (rounded off to four decimal values)
Step-by-step explanation:
The diameter of the semicircle is 14 units
The radius of the semicircle is thus 14 ÷ 2 = 7 units
Area of a semicircle is given by: 
× π × r²
In our case, the area is = × π × 7² = 76.9690200129 square units
Or 76.9690 square units (rounded off to four decimal values)
The circumference of a circle of given diameter d is pi*d.
Thus, if the diameter is d = 6 cm, the circumference of the circle is (6 cm)*pi.
