Answer:
a)Angle Angle Angle
d)Angle Side Side
f)Side Side Angle
Step-by-step explanation:
The postulates that are used to prove the triangles congruent are:
1)Side Side Side
2)Side Angle Side
3)Angle side Angle
4)Angle Angle Side
5)Hypotenuse Leg
Other than these postulates none can be used to prove the triangles congruent.
The choices which are not triangle congruence postulate are:
a)Angle Angle Angle
d)Angle Side Side
f)Side Side Angle
Answer:
C = πd = 14π = 14 * 3.142 = 43.988
Answer:
Step-by-step explanation:
Statistically this is valid
But, in Alaska average daytime summer temperatures range from approximately 55 to 78 °F (12.8 to 25.6 °C); average daytime winter temperatures are about 5 to 30 °F (−15.0 to −1.1 °C). SO, they don't need cooling when compared to rest of the USA. Therefore this will not be valid.
Answer:
Width of the rectangle = 15 inches
Length of the rectangle = 25 inches
Step-by-step explanation:
Let the width of the rectangle = k inches
So, the length of the rectangle = (2k -5) inches
Perimeter = 80 in
Perimeter of a rectangle = 2 (Length + Width)
⇒ 80 = 2(k + (2k -5)
or 80 = 6k - 10
⇒ 6k = 80 + 10 = 90
or k = 90 / 6
⇒ k = 15
So the width of the rectangle = k = 15 inches
And the length of the rectangle = 2k -5 = 2 x 25 - 5 = 25 inches

Answer:
372 m²
Step-by-step explanation:
A vertical line down the center of the figure will divide it into two congruent trapezoids, each with bases 13 and 18, and height 12.
The area of one of them is ...
A = 1/2(b1 +b2)h
So, the area of the two of them together is ...
A = (2)(1/2)(b1 +b2)h = (b1 +b2)h
A = (13 m + 18 m)(12 m) = 372 m²
