Answer:
Hello :
4x² - 8x +3 = 0
4 ( x² - 2x +3/4 ) = 0
4 ( (x² -2x +1) -1 + 3/4) = 0
4 ((x-1)² - 1/4 ) =0
(x-1)² - 1/4 = 0
(x-1)² - ( 1/2 )²=0
( x - 1 -1/2 ) ( x - 1 +1/2 ) = 0
( x - 3/2) ( x - 1/2) = 0
x - 3/2 = 0 or x - 1/2 = 0
two solutions : 3/2 ; 1/2
-- A fraction always means division.
To change a fraction to its decimal form, DO the division.
3/5 = 3 ÷ 5 = 0.6
-- To change a decimal to percent,
move the decimal point 2 places that way ===> .
0.6 = 60%
Answer:
∠A = 45°
Step-by-step explanation:
It is given that,
sin A = sin B
∠C is a right angle.
If sin A = sin B, it means
sin 45 = sin 45 =
It means that angle A and angle B is 45 degrees.
Answer:
