Answer:
Angle A = 50
Step-by-step explanation:
We know the 3 angles of a triangle add to 180
A + B+C = 180
2x-10 + 70 + x+30 = 180
Combine like terms
3x+90 = 180
Subtract 90 from each side
3x+90-90=180-90
3x = 90
Divide by 3
3x/3 = 90/3
x = 30
We want to find angle A
Angle A = 2x-10
= 2(30) -10
= 60-10
= 50

Step-by-step explanation:
Answer:
it would be 3 8/10
Step-by-step explanation:
you have to find a common multiple and it would be 10 thin you add them up 7/10+1/10=8/10 plus you have to put the 3 with the 8/10
Answer:
Step-by-step explanation:
Calculating the volume of a cylinder is very similar to determining the area of a prism. You can ... Recall that the area of a circle is equal to pi times the radius squared. ... V = Π(3.6)2(4) Here we started by replaced r with the radius and h with the height. ... V = 5400Π mm3 ← If you are
T= 1.272..
12.5t = 15.9
Therefore t= 1.272
