The side opposite the 30o angle is 1/2 W. That is just a property of a 30 - 60 - 90 triangle. Use that fact to set up the pythagorean relationship.
w^2 = (1/2 w)^2 + (7 * sqrt(3)) ^2
w^2 = 1/4 w^2 + 49*3
w^2 = 1/4 w^2 + 147
3/4 w^2 = 147
w^2 = 147 * 4/3
w^2 = 49 * 4 = 196
w = sqrt (196)
w = 14
Hello,
spinner has 1 yellow, 2 red, 3 blue and 2 green sections. What is the probability of not getting a yellow?
to find the probability to not get a yellow you have to know the total of color which is
1+2+3+2=8
and its 1 yellow
So the probability of not getting a yellow is 1/8
hope this help
Answer:
answer is y = 3/4x - 5
Step-by-step explanation:
picture below.
The 3/4 comes from the line. You would use rise over run to find the slope, which in this case is 3/4. and the -5 is basically the y-intercept
Answer:
(a) P = 4x+10
(b) x = 6
Step-by-step explanation:
(a) The perimeter is the sum of the side lengths:
P = AB +AC +BC = 2x +2x +10
P = 4x+10
__
(b) For P=34, the value of x is ...
34 = 4x +10 . . . .substitute given value for P
24 = 4x . . . . . . . subtract 10
6 = x . . . . . . . . . .divide by 4
