30 students
Step-by-step explanation:
Yesterday: 1/3 of the 75 students (75 / 3) = 25 students
There are now 50 students remaining to give their speeches.
Today: 2/5 of the 50 students (50 / 5 = 10 x 2 ) = 20 students
50 - 20 = 30 students remaining to give their speeches.
Step-by-step explanation:
just multiply the 2 together to get the area
it would just be

use the distributive property

unless you want to simplify the answer, this would be the answer
simplified, it would be

⇒.0625
Answer: 
⇒.0625
Sin(2x-8)=cos(90-2x+8)=cos(6x-6).
So 98-2x=6x-6, 104=8x, x=13.
2x-8=18, 6x-6=72. The smaller angle is 18 and the larger angle is 72.
