Assuming cos means cos(x);
Combine all like terms: cos(x)(√2 - 12)= -1
Isolate x: cos(x)= -1/(√2 - 12)
cos(x)=0.0944
x=cos⁻¹(0.0944)
x= 84.57 degrees or (360-x=275.42 degrees)
Hope I helped :)
Answer:
x=2/5, y=-24/5. (2/5, -24/5).
Step-by-step explanation:
y=-2x-4
y=1/2x-5
----------------
-2x-4=1/2x-5
-2x-1/2x-4=-5
-4/2x-1/2x=-5+4
-5/2x=-1
5/2x=1
x=1/(5/2)
x=2/5
y=1/2(2/5)-5
y=1/5-5
y=1/5-25/5
y=-24/5
Answer:
Step-by-step explanation:
get them some multiplication charts and use some examples like oreos or any type of cookies.
Your answer would be 24 and 168
take the 48 and divide by 4 to get the 1st one then just multiply 24 by 7 and you get 168
C because the formula to find the are of a circle is A=(pi) * radius^2. To find the radius from diameter, just divide by two. So 60/2= 30 so now you can just plug in and 30 * 30 is 900 and 900 * pi, or 3.1415926535, is about 2827
