Answer:
x = 162
Step-by-step explanation:
the sum of the interior angles of a quadrilateral = 360°
sum the interior angles of the quadrilateral and equate to 360
90 + 60 + x + 48 = 360 , that is
198 + x = 360 ( subtract 198 from both sides )
x = 162
If you would like to know the next value, you can calculate this using the following steps:
1/6, 1/9, 2/27, 4/81, x = ?
1/9 / 1/6 = 1/9 * 6 = 6/9 = 2/3
So, if we would like to know what is the next value of this geometric sequence, you have to multiply 4/81 by 2/3:
4/81 * 2/3 = 8/243
The correct result would be 8/243.
Answer:
80
Step-by-step explanation:
75 60
------ = ------
100 x
100 x 60 = 6000
75x = 6000
x = 80
Well the first thing you have to do is find out how many times 7 goes into 50 whole. This is 7. So then you take the answer to (7x7) from 50 which gives you one, and put it over 50. This equals 7 + 1/50
Answer:
The base of the ladder has a length of 8 ft.
Step-by-step explanation:
We have to draw a triangle, as the figure attached.
The hypothenuse of the triangle is the length of the ladder (17 ft).
The height on the wall that the ladder reach is the adjacent (15 ft).
The base of the ladder is our unknown quantity X.
We will use the Pythagorean theorem to express the relation between these numbers:
The base of the ladder has a length of 8 ft.
