Answer:
126 cubic inches.
Step-by-step explanation:
8 × 4.5 × 3.5 = 126
In a triangle, the three angles ALWAYS add up to 180°
x + (6x + 10) + (x + 2) = 180
8x + 12 = 180
8x = 168
x = 21
To calculate the measure of each angle, substitute x in:
Angle A: 21
Angle B: 6(21)+10
Angle C: 21 + 2
Do the angles add up to 180 degrees? Just add the answer for A B and C and see if the sum is 180. It should be 180, if it isn't something is wrong with the calculation.
