Answer:
5.4
Step-by-step explanation:
I am not really sure about this type of problem, but a diameter has to cross the midpoint of the circle the dark dot and hit two point on both side of the circle. Yet the line 9.6 is not a diameter since it didn't go through the center, so the diameter has to be longer than 9.6. But x is looking for radius. so divide 9.6 by 2 u get 4.8 but that is not a diameter and the real diameter is longer that mean the radius is longer so the only answer is 5.4
Answer: 3-4-5-6-9-15-16-25
Step-by-step explanation:
They are called powers of 10.
Hello!
It is given information that this triangle is a right triangle, meaning that the Pythagorean Theorem can apply here.

We can set the length of a leg as an unknown variable
.

Remember that it is the whole
term being squared, meaning that it'll simplify to
, not
.




This means we can plug back in to find the sides.
The hypotenuse would be
, or 4.2.
And the legs would be 1.4 and 4, respectively.
Hope this helps!
The acute angles of a right triangle are complementary, so
α + β = 90
(5x/3 +20) + (2x/3) + 14) = 90 . . . . . . substitute given values
7x/3 +34 = 90 . . . . . . . . . . . . . . . . . . . collect terms
7x/3 = 56 . . . . . . . . . . . . . . . . . . . . . . . subtract 34
x = (3/7)*56 = 24 . . . . . . . . . . . . . . . . . multiply by 3/7
Then the value of α is ...
α = 5*24/3 +20 = 60
