Answer:
1. 75
Step-by-step explanation:
take boths numbers add them up then divide but by 2
It is 512 because you have to multiple 64x8=512 you should have figure that out and add 512+2=514 do you get it now ?
Answer:
c cause it says length = 5x
Answer:
X= 17
Step-by-step explanation:
In the picture above , you see that
BAE =~ DAE
So , just substitute the equation of each other and solve for x.
That's it.
It looks like the length of a and b should be the same. You can use the Pythagorean theorem (only works with right triangles):
a² + b² = c² (c is the hypotenuse or the longest side of the triangle, a and b are the other side lengths of the triangle)
a² + (4)² = (5)²
a² + 16 = 25
a² = 9
a = 3
a and b have a length of 3
