So here we can find out that the two angles are vertical angles. That means that they have the same measure. So what we need to do is set them equal to each other:
2x+20=3x-30
x=50
Answer:
3
Step-by-step explanation:
1/5 / 1/15 = 3
Answer:
x = 3√5
Step-by-step explanation:
we can use the Pythagorean Theorem twice, first to find the longer leg of the left triangle:
7² + b² = 10²
b² = 100-49
b² = 51
b = √51 which we can simplify to be √9·√3·√3 = 3·3 = 9
we can use the Pythagorean Theorem next to find 'x':
x² + 6² = 9²
x² + 36 = 81
x² = 45
x = √45 = √9·√5 or 3√5
Answer:
1) Vol. of prism=l*b*h
=4*2*9
=72cm^3
2)Vol. of pyramid =1/3(4*2)*9
=4*2*3
=24cm^3
3)Volume of pyramid is 24/72 *100=100/3=33.3%
NO,
Divide 3000 by 6 and then you will get the answer
