He is not correct. If this is to be an equilateral triangle then all the angles must be the same measure. That means that 180/3 = 60°. They all have to equal 60°. If one of the angles measures 4x-12, then 4x-12=60. Solving for x, we will add 12 to both sides to get 4x=72. x here is 18. For the other angle measuring 2x+26, we would do the same. 2x+26=60. Subtract 26 from both sides to get 2x= 34 and x = 17. He was way off.
Answer:
Domain { 0 ≤ r≤ 18}
Range = {0≤ c ≤ 31.5}
Step-by-step explanation:
The domain is the values that r can take
He can goes on each ride up to 1 time
R can be from 0 rides to 18 rides since there are only 18 rides
Domain { 0 ≤ r≤ 18}
The range is the output
If r = 0 then he spends no money
if r =18 then 1.75*18 =31.5
Range = {0≤ C(r) ≤ 31.5}
Bria ordered 145 centimeters of fabric. Jayleen ordered 1.5 meters of fabric. Who ordered more fabric?
SinA=8/17, so arcsin(8/17) is your angle of A (around 49 degrees). 90-A is your angle for B
