Answer:
A) x = 10-/3, y = 20
Step-by-step explanation:
You have to use the Pythagorean theorem but there is a little twist here since a square has has equal sides. So:
x^2+x^2=8
2x^2=8
2/2x^2=8/2
x^2=4
√x^2=√4
x=2
The side of the square is 2.
So now the area of a square is:
Side×Side
2×2=4
The area of the square is 4 centimetres
Answer:
S = 2
Step-by-step explanation:
1st step: Simplify both sides of the equation
4/5 s - 3/4 s = 1/10
4/5 s + -3/4 s = 1/10
(4/5 s + -3/4 s) = 1/10 (combine like terms)
1/20 s = 1/10
1/20 s = 1/10
step 2: multiply both sides by 20
20 * (1/20 s) = 20 * (1/10)
s = 2
Hope this helped!
M∠CBT is not 120°.
You have to notice the start of the measure of the angle is on the point of C. It is the 0°.
If the segment BT is straight up from the point of B, its angle will be 90°.
Since the segment does not form a right angle, its measure of angle is less than 90° but more than 0°
