Answer:
45
Step-by-step explanation:
Answer:
because .47 rounded up is .5
Answer:
See below
Step-by-step explanation:
<u>The coordinates of given points on the graph:</u>
- A(-1, 3), B(4, 1), C(1, 7), D(6, 5), E(1.5, 6), F(3, 3)
<u>Use of slope formula:</u>
11.........................................................................
a) <u>Slope of AB</u>:
b) <u>Slope of CD</u>:
c) AB and CD are parallel as slopes are same
12.........................................................................
a) <u>Slope of EF</u>:
b) <u>Slope of AD</u>:
c) EF and AD are neither parallel nor perpendicular
U see that 80 degree angle in the lower right side...it is congruent to the angle vertical to it....because vertical angles are congruent. So the lower right angle is 80 degrees.
Now , on the lower left side u have ur 123 degree angle. The angle adjacent to the 123 degree angle (the angle we r looking for) forms a straight line and when added, will equal 180 degrees
180 - 123 = 57. So the lower left angle in ur triangle is 57 degrees
ok...the interior angles of a triangle all add up to 180 degrees....
57 + 80 + x = 180
137 + x = 180
x = 180 - 137
x = 43......<==
It sounds like D) technology is the best fit here.
Technology is used to help provide people with the things they need, for example clean water.
