Answer:
Step-by-step explanation:
To work out the percentage of the circle shaded blue, we first must work out the area of the whole circle.
Area of the whole circle =
Now we need to work out the area of the blue 2d torus, by finding out the area of the blue circle, then subtracting the area of the innermost white circle.
Blue shaded area =
Now we have the total areas of each, we can work out the fraction of blue to non blue by dividing the blue area by the total area, and then working out the percentage by multiplying by 100.
The only way you have of finding the length of the missing side is
to ASSUME that the lengths of all 3 of them form a Pythagorean
triple. You know that you can go ahead and do this when you see
the little red 'corner' drawn in one vertex of the triangle. Then you
know that the angle is a right angle, the triangle is a right triangle,
and the sides form a Pythagorean triple.
Then (missing side) = √( 1.7² - 1.5²)
= √(2.89 - 2.25)
= √0.64 = 0.8 .
Without that little red box corner-symbol, there would be no way.
You would not stand a chance.
If you can separate the figures and the segment, or angle in question, is the same, the reflexive property of congruence can be used in the proof. ... Separating the two triangles, you can see Angle Z is the same angle for each triangle. Since they are the same angle, the angle is congruent to itself.
Answer:
:)
Step-by-step explanation:
well if you take 35x, which is 35 times whatever, + 70, you get y. so the first one is 35(1) + 70 = 105.
so i’ll go in order
35 x 1 + 70 = 105
35 x 2 + 70 = 140
35 x 3 + 70 = 175
35 x 4 + 70 = 210.
just multiply then add 70
hope this helped
