Answer:
y is equal to 2 and x is equal to 31 degrees.
Step-by-step explanation:
In order to find this, we must note that similar parts of congruent triangles are congruent. Since y is congruent to the part that is labeled 2, then it is an easy comparison.
x is a bit trickier. For this one, we must find the missing angle of the first triangle. To get that, we must subtract the given angle and the right angle from 180. This will give us x.
180 - 59 - 90 = x
31 = x
<span>The central angle in a minor arc is acute. In a minor arc, the angle must be less than 180˚. However, it doesn't have to be less than 90˚. So the central angle is sometimes acute.
hope this helps u leave a like if it does</span>
Answer:
x = 4
Step-by-step explanation:
It is given that 
, and we have to solve the given equation for x.
Now, we have
Squaring both sides we get
![[\sqrt{(x - 3)}] ^{2} = [\sqrt{x} + 3]^{2}](https://tex.z-dn.net/?f=%5B%5Csqrt%7B%28x%20-%203%29%7D%5D%20%5E%7B2%7D%20%3D%20%5B%5Csqrt%7Bx%7D%20%2B%203%5D%5E%7B2%7D)
⇒ x - 3 = x + 6√x + 9 {Since we know the formula of (a + b)² = a² + 2ab + b²}
⇒ 6√x = - 12
⇒ √x = -2
Again squaring both sides we get
⇒x = 4 (Answer)
