15 * 28 = 420. Should be your answer.
Answer:
36°, 36° and 108°
Step-by-step explanation:
let the equal angles be x then the third angle = 3x
The sum of the 3 angles in a triangle = 180°, thus
x + x + 3x = 180, that is
5x = 180 ( divide both sides by 5 )
x = 36
and 3x = 3 × 36 = 108
The 3 angles are 36°, 36° and 108°
Answer:
The awnser is "The slope of line B is 4"
Answer:
This equation is in standard form: ax 1+bx+c=0. Substitute 9 for a, 16 for b, and −112 for c in the quadratic formula 2a−b±b2−4ac.x= 2×9−16± 16^2−4×9(−112)Square 16.x=2×9−16±256−4×9(−112) Multiply −4 times 9.x=2×9−16± 256−36(−112) Multiply −36 times −112.x=2×9−16±256+4032 Add 256 to 4032.x=2×9−16±4288 Take the square root of 4288.x=2×9−16±8+67 Multiply 2 times 9x=18−16±8=67
