If two angles are equal, then they are both obtuse
Answer:
a =12*sqrt(2)
Step-by-step explanation:
3. The Pythagorean theorem states
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2 +21^2 = 27^2
a^2 +441 =729
Subtract 441 from each side
a^2 +441-441 = 729 -441
a^2 =288
Take the square root of each side
sqrt(a^2) = sqrt(288)
sqrt(xy) = sqrt(x)sqrt(y)
a = sqrt(144)sqrt(2)
a =12*sqrt(2)
7:54...10:55 - 33 minutes is 10:22. Then subtract 2 hours, brings you to 8:22. Then subtract 28 minutes, and is 7:54
Answer:
P = 20x + 6y + 10
Step-by-step explanation:
The perimeter (P) of the figure is the sum of the sides , that is
P = 2x - y + 3x + 5y + 12 + 6x + 9x + 2y - 2 ← collect like terms
= 20x + 6y + 10
