Try this solution (note, this is not the only way):
Q1: if sin(x- 3pi/2)=-sin(3pi/2- x)=--cosx=cosx, then sin(x- 3pi/2)=cosx and sin(x- 3pi/2)=<u>7/25</u>.
Q2: if tan(x)=√3 and x∈(180°;270°), then x=arctan√3+180°=60+180=240°.
If x=240°, then sin(x-210°)=sin30°=<u>0.5</u>.
<h3>Answer:</h3>
There are more red marbles in the bag.
<h3>Explanation:</h3>
The fraction of red marbles is 1/3 = 3/9. That is a larger fraction than the fraction of green marbles, which is 2/9.
Answer:
C, D
Step-by-step explanation:
I assume your problem statement actually says
x - 54 > -76
x > -22
then the answers
C, D
are part of the solution set.
the others are not.
Answer:
D= -9/13
Step-by-step explanation:
13d+8−8=−1−8
13d=−9
13d
/13 = −9
/13

Hey!!
here is your answer >>>
let's find x first ,
2x + 48 = 180
2x = 132
x = 66!.
there is a right angle,
the angle below the right angle is also 90°
angle y would be ,
180 - (90+ 48)
180- 138
=> 42
answer is 42!.
if helped!. brainliest
