Using the cosine ratio in the right triangle
cos A =
=
=
, then
∠ A =
(
) ≈ 44.42° ( to the nearest hundredth )
Is this a STARR test?
A. Divide 99 by 250
Step-by-step explanation:
since
25⁰= 1 minute
x⁰ = 11 minutes
cross multiply
25 x 11= x
x= 275⁰
temperature after being turned on=275⁰
temperature after 11 minutes= 275⁰ + 75⁰= 350⁰
temperature(x) after being turned on
25tt=x
temperature (x) after minutes
x= 25tt + 75⁰
Multiply both sides by 2 to cancel out the 1/2 and you get 2a=bh then divide both sides by h to isolate b and you get (2a)/h=b
