Answer:
B
Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ FES is an exterior angle of the triangle , then
57° + ∠ F = 142° ( subtract 57° from both sides )
∠ F = 85°
Answer: 2.11X=11.41
X=9.3
or
211x=1141

Answer:
answer is 175
Step-by-step explanation:
i solved it by similarity in triangle small triangle and big triangle are similar to each other.
The first angle is 76 and the second angle is 14. You can check this by doing 14+5=19 and then multiply that by 4.
So, to factor out the equation x²+12x+35, first multiply the first and last numbers.
1×35=35
So, you need to find the multiples of 35 that add up to 12.
So, you find 7 and 5. These two numbers are the magic numbers that will be used as the correct factored form of x²+12x+35, because:
>7×5=35
>7+5=12
So, using these two numbers, you get your factored form as:
(x+5)(x+7)
