These angles are equal due to the interior angles rule in which alternating interior angles are congruent
therefore 5x+12=117
5x=105
x=21
56 is 80% of 70.
70 x 0.80 = 56
To find the base number, divide 56 by 0.80:
56 / .8 = 56 / (8/10) = 56 x (10/8) = 560/8 = 70
Answer:
29/12
Step-by-step explanation:
In an isosceles triangle, two sides are equal.
Therefore:
25/6+25/6+u = 10 3/4
50/6+u=43/4
u=43/4-50/6
u=43/4-25/3
u=129/12-100/12
u=29/12
The cross-section of a cylinder is in the shape of a Circle
They are equal (the sign would be =)
