Answer: 9
is the value of "x".
It is 29 I might be wrong though
Answer:
x = 8.75, y = 8.125
Step-by-step explanation:
The triangles are similar thus the ratios of corresponding sides are equal, that is
=
( cross- multiply )
8x = 70 ( divide both sides by 8 )
x = 8.75
And
=
( cross- multiply )
8y = 65 ( divide both sides by 8 )
y = 8.125
To solve this polynomial equation, we first factor the left side.
To factor x² + 8x + 12 = 0, look for factors of 12 that add to 8.
These factors are 6 and 2 so we have (x + 6)(x + 2) = 0.
So either x + 6 = 0 or x + 2 = 0 and solving for
x in each equation, our answer is {-6, -2}.
2(30)=60+30=90. thats a right angle which is 90 degrees so the answer is 30
