Answer:
4x°= 4x18= 72°=measure of angle SQR
Step-by-step explanation:
6x +4x = 180
10x = 180
x = 180/10
x= 18°
because m L SQR =4x°
now place the value of x in the above equation
m L SQR = 4 x(18°)= 72°
7x² = 9 + x Subtract x from both sides
7x² - x = 9 Subtract 9 from both sides
7x² - x - 9 = 0 Use the Quadratic Formula
a = 7 , b = -1 , c = -9
x =
Plug in the a, b, and c values
x =
Cancel out the double negative
x =
Square -1
x =
Multiply 7 and -9
x =
Multiply -4 and -63
x =
Multiply 2 and 7
x =
