Answer:for 5
Step-by-step explanation:1,5
The unknown side lengths are
Large triangle 10
Medium triangle 2
Small triangle 12/5 or 2.4
Step-by-step explanation:
EFD to ABC is 0.4 or 2/5
EFD to GHI is 0.24 or 6/25
ABC to GHI is 0.6 or 6/10
Anything multiplied by 0 =0
So what is left is 90x100x12x13x34 which is=47,736,000
Hi, We have a isosceles triangle.
Then,
There is two angles = (2x +2)°
As the sum of angles = 180° To the any triangle.
Then we wiil stay with:
(2x+2)° + (2x+2)° +(3x+1)° = 180°
Canceling °
2x+2+2x+2+3x+1=180
7x +5 = 180
7x = 180-5
7x = 175
Passing 7 dividing 175
x = 175/7
x = 25
This would be your answer!
Answer:
x = (1/2) (-9 ± √73)
Step-by-step explanation:
Using completing the square method
x²+9x+2=0
x²+9x = -2 (complete the square by adding (9/2)² to both sides)
x²+9x + (9/2)² = -2 + (9/2)²
( x + (9/2) )² = -2+ (9/2)²
( x + (9/2) )² = -2+ (81/4)
( x + (9/2) )² = 73/4
x + (9/2) = ± √(73/4)
x + (9/2) = ± √(73) / 2
x = -(9/2) ± √(73) / 2 (factorize out (1/2) )
x = (1/2) (-9 ± √73)
