Let x be the degree of angle a.
Angle b: 20+3x
Angle c: 55+x
We know that all angles add up to 180 degrees.
180=x+(20+3x)+(55+x)
180= 5x+75
180-75=5x
105/5=x
21=x
Angle a: 21 degrees
Angle b: 20+3(21) => 83 degrees
Angle c: 21+55 => 76 degrees
Hope I helped :)
I^3=-i
therefor -27i=(3i)^3
so we can get a sum of 2 perfect cubes
a^3+b^3=(a+b)(a^2-ab+b^2)
so
remember that i²=-1
x^3+(3i)^3=(x+3i)(x²-3xi-1)
Answer:
$12 per tool kit
Step-by-step explanation:
110-14=96
96/8=12
Length x width x height, 12 x 5 = 60, multiplied by 2 1/4 = 540. if it’s the fractions thats confusing you, to turn a fraction into a decimal you multiply the whole number by the denominator, then add the numerator.
