The sum of interior angles of a triangle must add up to 180 degrees
if the triangle has an angle that is greater than 90 degrees, then it is considered obtuse
if the triangle has an angle that is 90 degrees, then it is considered right
if all angles are less than 90, then it is acute
find the missing angle "x"
180=60+80+x
is angle x less than, greater, or equal to 90 degrees?
Answer:
The equation that models the relationships between
, the number of hours Mark reads, and ,
the number of pages of the book he reads is:

Step-by-step explanation:
Given:
Mark reads 42 pages every
hour.
The number of hours is given by = 
The number of pages is given by =
The equation can be modeled as:

where
represents rate of change and
represents the y-intercept or the initial value.
Rate of change =
The initial value
as Mark starts reading from 0.
So, the equation is:

The bench is cost $350
T+B=654
T=B-46
2B=700
B=350
Answer:
- 18
Step-by-step explanation:
note that | 9 | = 9 , thus
- 2 | 9 | = - 2 × 9 = - 18
The answer is D
Explanation:
The -2 on the X is reversed so it becomes +2 on the x-axis
The +2 at the end of the equation makes the graph go up 2
