Answer: A
<u>Step-by-step explanation:</u>
≅ 
⇒ ∠XOY ≅ ∠ZOY
≅ 
since they are both a radius
≅ based on reflexive property
∴ ΔXOY ≅ ΔZOY by SAS
So, 
≅ 
by CPCTC
ZY = 10.2 is given
so, XY = 10.2 by substitution property
J=15b/10g
S=21b/g w/ the ratio 3/2 (15/10=3/2)
1) Form an equation (21/g=3/2).
2) Since you are trying to find the denominator, multiply 3/2 so that the numerators are the same (3×7=21 2×7=14).
3) The answer will be whatever the denominator is at the end.
The answer is there are 14 girls in Steven's class.
The volume of a cone is V= (1/3)pi r²h
it was given
h=12cm
radius=3cm
the volume of the first cone is V1= 1/3)pi r²h1
where h1= h/2=6cm
so its volume is V1=1/3)xpix3²x6=56.52cm^3
and since the two cones are identical so V1=V2=<span>56.52cm^3,
we need </span><span>56.52cm^3 or salt </span>
Answer:
m = 35°
Step-by-step explanation:
Supplementary angles, sum = 180°
m + 145° = 180°
m = 180° -145°
m = 35°
