25x^2 = 16
divide each side by 25
x^2 = 16/25
take the square root of each side
sqrt (x^2) = +- sqrt(16/25)
x = +- sqrt(16)/sqrt(25)
x = +- 4/5
x = 4/5, - 4/5
4x + 9 = 68
Subtract 9 from both sides:
4x = 59
Divide both sides by 4
X = 59/4
X = 14.75
The measure of angle X is 83 degrees.
180 subtract 53 and 44 gives you 83.
C x=4y can no be true.
x=4y, total phonographs are 5y
5y cannot be 24 if y is an integer.
Measures of angles are X = 102° and Y = 78°
Step-by-step explanation:
- Step 1: Let ∠X = 24 + Y. As they are supplementary angles, ∠X + ∠Y = 180°
⇒ 24 + Y + Y = 180
⇒ 2Y = 180 - 24 = 156
⇒ Y = 156/2 = 78°
- Step 2: Find measure of X
⇒ X = 24 + Y = 24 + 78 = 102°
