20-10=10 therefore X=10
10+10=20
If angle BCD measures 70° then so does angle DBC (because you have formed an isoceles triangle inside the larger ΔABC and the two legs are equal so the two angles have to be equal. So we have a two 70° angles which leaves 40° for the 3rd angle, which is ∠BDC.
Since ∠BDC and ∠ADB are supplementary (180°) - that leaves 140° for ∠ADB and is our answer
Answer:
55
Step-by-step explanation:
Add the numbers 5 + 8 and you get 13. Multiply 13 x 2 which is 26. Add 33 + 26 and you get 59. Then, subtract it by 4 and you get 55.
Answer:
18
Step-by-step explanation:
3^4=9*9=81
14-5=9
81/9=9
9*2=18
Answer:
24 units
Step-by-step explanation:
The volume of the cylinder = πr²x
Where r is the radius of the base and x is the height of the cylinder.
πr²x = 1,176π
π×(14/2)²x = 1,176π
dividing by π both sides,
(14/2)²x = 1,176
7²x = 1,176
49x = 1,176
x = 1,176/49
= 24 units
