Hello!
To find the area of the trapezoid, you use the formula A=1/2h(a+b), where a and b represent the two base lengths.
Since we already know the two bases and the height, we can just plug them into the equation to find the area.
A=1/2·15.4(26.7+9.9)
A=1/2·15.4(36.6)
A=1/2·563.64
A=281.82
The area is 281.82 ft².
I hope this helps!
21^2/0.219 = 2013.69863
2 significant figures are the 20, so the answer is 2000
Answer:
degree = 120°
A =67 cm²
d=?
note : diameter= 2×radius
area of a circle = πr²
67=22/7 ×r²
67×7=22r²
469=22r²
r²=469/22
r²=21.32
r=4.62
diameter=2 × radius
d= 2× 4.62
d=9.24
d=9
I hope it helps :)
Answer:
We can't prove this with the SAS postulate.
Step-by-step explanation:
SAS means that two sides and the angle between those two sides are equal.
Side Angle Side (SAS)
That's why we can't prove this with the SAS postulate.
