Answer: adjacent and hypotenuse
Step-by-step explanation: Cos theta is adjacent/Hypotenuse
Perimeter is 2(2x+5)+2(x-2) which is 4x+10+2x-4 which is in turn 6x+6. 6x+6 is the perimeter. Hope I helped!
If the hypotenuse is equal to 11, then we can plug it into the Pythagorean theorem. So we get a^2+x^2=121. So we take the square root of both sides, sqrt(a^2+x^2)=11. So we take a^2 and x^2 out of the square root. We get a+x=11. So now we have two equations, a+x=11 and a^2+x^2=121. I’ll leave the rest of solving equations to you.
Hint: a=11-x
You can plug that into a^2+x^2=121
Answer The answer is y=7/5
Step-by-step explanation:
Answer:
33/2
Step-by-step explanation:
6+2x -20= 2×2 +15
-14+2x=19
add 14 to both sides
2x=33
divide 2 in both sides
x=33/2
