Together, they make an acute angle. An acute angle is any angle less than 90°. If you look at this picture, you can tell it is less than 90°.
1.6 : 4
1.6 is also equal to 8/5
therefore,
8/5 : 4
(8/5)/4
**get the reciprocal of the denominator (4) which is equal to 1/4**
(8/5)*(1/4)
(8/4)*(1/5)
2*(1/5)
2/5
two fifth is the answer
Answer:
x = 12
Step-by-step explanation:
67+42+6x-1=180
108+6x=180
6x=72
x=12
Altogether there are 8 parts. Thus, the part that is yellow is 3/8, or 37.5%
If the equation is given in factored form and the roots are real, then you can identify the x-coordinate of the vertex by averaging the 2 root values. For example, if the roots are -2 and 5, the x-coord. of the vertex is (-2+5)/2, or 3/2.
Once you have this x value, subst. the value into the given equation to calculate y. Then write the vertex as (x,y).
