Answer:
x=3
Step-by-step explanation:
if the equation is 2x=6 then you'd do 6/2 and 2x/2 to cancel out the 2 and get x=3
Maybe:
Cos90=0
I’m not sure of the question here
Answer:
Step-by-step explanation:
When thermal energy is added to a substance, its temperature increases, which can change its state from solid to liquid (melting), liquid to gas (vaporization), or solid to gas (sublimation). ... When the pressure exerted on a substance increases, it can cause the substance to condense.
Answer:
circumference=50.24 cm
area=200.96 cm²
Step-by-step explanation:
r=16/2=8
circumference=2πr=2×3.14×8=50.24 cm
area=πr^2=3.14×8²=200.96 cm²
Answer:
1:
<A=½(arcJL)=½(70+120)=35+60=95°
[inscribed angle is half of central angle]
2:
<W=½arcVX=½(130)=65°
[inscribed angle is half of central angle]
3.
<E=½(arcDC)=½(90)=45°
[inscribed angle is half of central angle]
4.
<R=½(arcXZ)=½(110+62)=86°
[inscribed angle is half of central angle]
5.
<B=½(arc DC)=½×104°=52°
[inscribed angle is half of central angle]
6.
<K=90°
[inscribed angle in a diameter is complementary]
<K+<J+<L=180°(sum of interior angle of a triangle]
<L=180°-90°-53°=37°
again
arc JK=2×<L=2×37=74°
