Answer:
77760 meters I guess
Step-by-step explanation:
When simplifying expressions, you use the distributive property and combine like terms.
4(3x - 2) + 6x(2 - 1)
12x - 8 + 12x - 6x <--- Used the distributive property for both parentheses.
6x - 8 <--- Combined like terms.
So, 6x - 8 is the answer.

Answer:
angle A = 18°
angle B = 36 + 3(18) = 90°
angle C = 54 + 18 = 72°
Step-by-step explanation:
A triangle is a shape with 3 sides. The total angle of a triangle is 180°. This means the sum of all the angle is 180°.
Let
angle A = a
angle B = 36 + 3a
angle C = 54 + a
The sum of angle A, B and C should be equals to 180°. Therefore,
a + 36 + 3a + 54 + a = 180°
collect like terms
5a + 90 = 180
5a = 180 - 90
5a = 90
divide both sides by 5
a = 90/5
a = 18°
angle A = 18°
angle B = 36 + 3(18) = 90°
angle C = 54 + 18 = 72°
