Answer: True
One angle of a right triangle = 90°
Let x = the acute angle of one angle.
Let y = the angle of the other angle.
Because the sum of angles in a triangle is 180°,
x + y + 90 = 180
x + y = 90
y = 90 - x
Therefore the angles for each of the two triangles are
x, 90° - x, 90°.
The two triangles are therefore similar because of AAA (Angle, Angle, Angle).
Answer:
1/6
Step-by-step explanation:
To find the common ratio, you compare a few pairs of consecutive terms, by dividing an element by its predecessor.
12 / 72 = 1/6
2 / 12 = 1 / 6
1/3 / 2 = 1 / 6
The ratio is constant... so that's your common ratio to go from one term to the next.
To go from one term to the next, you have to multiply by 1/6.
Answer:
x=8
Step-by-step explanation:
We can use the Pythagorean theorem to solve
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
6^2 + x^2 = 10^2
36 + x^2 = 100
Subtract 36 from each side
36-36 +x^2 = 100-36
x^2 = 64
Take the square root of each side
sqrt(x^2) = sqrt(64)
x = 8
