Answer:
Step-by-step explanation:
60° , 60° , 60°
You have to factor this...
So you have started with this...
x²-x-2=0
If you factor this you will get
(x+1)(x-2)=0
This gives you two solutions...
x=-1, x=2
Hope this helps! Give me a five-rate and a thanks!
If you look at the rectangle properly, you can see that the diagonal creates two triangles, and if we only focus on one triangle, we can see that the bad of the triangle is 7 and the perpendicular height is 4
Using Pythagorean theorem we can figure out the hypotenuse, or the diagonal
C squared is equal to a squared plus b squared
7^2+4^2 is 65
Square root of 65 is 8.1
The equation to find the Volume of something is length*Width*height
therefore:
(I'm confused as to what <span>10/1/2 means so)
</span>
•on the assumption that 10/1/2 means 10 and a half - 10.5
then it would be - 15*10.5*2.5 = 393.75m^3
<span>•on the assumption that 10/1/2 means 10 divided by 1/2 then it would be:
</span>15*20*4 = 1200m^3
(z+1.2)/5=3.6
quotient: division
