Answer:
270 uits
Step-by-step explanation:
Answer:
x=13
Step-by-step explanation:
The two angles are vertical angles and vertical angles are equal
5x = 6x-13
Subtract 6x from each side
5x-6x = 6x-13-6x
-x = -13
Multiply each side by -1
x=13
Answer:
Step-by-step explanation:
The altitude to the hypotenuse of a right triangle create two smaller triangles, all of which are similar to the original. This means corresponding sides are proportional.
3. Using the above relationship, ...
short-side/hypotenuse = 8/y = y/(8+23)
y^2 = 8·31
y = 2√62
__
long-side/hypotenuse = z/(8+23) = 23/z
z^2 = 23·31
z = √713
__
short-side/long-side = 8/x = x/23
x^2 = 8·23
x = 2√46
_____
4. The picture is fuzzy, but we think the lengths are 25 and 5. If they're something else, use the appropriate numbers. Using the same relations we used for problem 3,
y = √(5·25) = 5√5 . . . . . . . = √(short segment × hypotenuse)
z = √(20·25) = 10√5 . . . . . = √(long segment × hypotenuse)
x = √(5·20) = 10 . . . . . . . . . = √(short segment × long segment)
n - 7 = 21, n= 28 should be right bc the difference of 28 and 7 is 21
Work shown above! Answer would be 2x^2 -16x + 30
