all angles in a triangle add up to 180º
1. 180-27-115 = 38º
2. 180-20-135 = 25º
3. 180-55-47 = 78º
4. 180-27-125 = 28º
5. 180-27-86 = 67º
6. 180-36-33 = 111º
7. 180-59-110 = 11º
angles on a straight line add to 180º or the exterior angle is equal to the sum of the opposite interior angle (i think that angle is 50 but if its not let me know)
8. 180-50 = 130º
Answer:
16225
Step-by-step explanation:
You need to multiply
Answer:
let m be minutes, p be pages
pages read = times(in minutes) * reading speed(pages per minutes)
p=m*(60/20)
p=3m
For every increase of a minute of reading time, pages that Wesly have read will increase by 3
Substitution
-2x+8=x^2-9x+18
x^2-7x+10=0
Factoring, we get
(x-5)(x-2)=0
x=5, x=2
If x equals 5,
y=-2(5)+8=
-10+8=
-2
Therefore, we derive our first solution:
<h2><u><em>
x=5,</em></u></h2><h2><u><em>
y=-2</em></u></h2>
Now we solve for our second x
If x=2,
y=-4+8=
4
Therefore, we derive our second solution:
<h2><u><em>
x=2</em></u></h2><h2><u><em>
y=4</em></u></h2>
<u><em></em></u>

Answer: 5 units
Step-by-step explanation:
5/2 = 2.5
they are 2.5 away on each side of 0 therefore the points are 5 units away from each other
