Answer:
x = 50
Step-by-step explanation:
The sum of the measures of the interior angles of a polygon of n sides is
(n - 2)180
This polygon is a quadrilateral with 4 sides. n = 4
(n - 2)180 = (4 - 2)180 = 2(180) = 360
The sum of the measures of the interior angles of the quadrilateral is 360 degrees.
We have angles of 110 deg, 2x deg, x + 10 deg, and 90 deg. We add their measures and set teh sum equal to 360. Then we solve for x.
x + 10 + 2x + 110 + 90 = 360
3x + 210 = 360
3x = 150
x = 50
Answer:
X=3
Step-by-step explanation:
What you have to do is minus 2 from 11 and you get 9
Now divide 3 into 9 and you get 3
x=3 you can also plug 3 for x to see if the equation is right
Answer:
if you toss a dice 30 times, you will roll a two 5 times.
Step-by-step explanation:
If you toss a dice once, the probability of rolling a 2 is 1/6, like you said.
So if you multiply your chances of rolling a 2 by 30, you get;
30.1/6 = 30/6 = 5
Answer:
s = 17 units
Step-by-step explanation:
The Pythagorean theorem applies:
8^2 + 15^2 = s^2
64 + 225 = s^2
289 = s^2
√289 = 17 = s
The value of s is 17 units.
