Since y=x+3 (given)
Put value of y in equation x+y=(-3)
x+x+3=(-3)
2x=(-6)
x=(-3)
Put x=(-3) in x+y=(-3)
(-3)+y=(-3)
y=0
So, x=(-3)
y=0
Step-by-step explanation:
Use the sine and cosine trig functions
21) cos(52)=13/x
x=13/cos(52)
x=21.1
22) sin(75)=6/x
x=6/sin(75)
x=6.2
Answer:
Theta = 59 degrees
Step-by-step explanation:
Here, we want to get the value of the marked angle
To do this, we use the appropriate trigonometric ratio
From what we have,
The side 42 ft is adjacent the angle given
The side facing the right angle is 82 ft
The trigonometric ratio that connects the adjacent and the hypotenuse is cosine. It is the ratio of the adjacent to the hypotenuse
Cos theta = 42/82
theta = cos^-1 0.5122
theta= 59.189
To the nearest degrees, this is 59 degrees
Answer:
4365.5 or 4365 1/2
Step-by-step explanation:
When you divide 8731 by 2 you will get a decimal.
But you will also get a fraction which is 4365 1/2.
Now you will have to answer with the for that best fits your problem.
