Answer:
81.5
Step-by-step explanation:
<G and <H are congruent
<F and <I are congruent
so the last two angles in both triangles must also be congruent
this means that <K and <J are congruent
so we can create this equation: <K = <J
substitute the angles with what we know: 4
= 6 - 40
add 40 to both sides and subtract 4 from both sides: 40 = 2
you get: 20 =
root square on both sides: 
= 
you get: y ≈ 4.5
substitute this into one of the equations for a missing variable:
6 -----> 6 (4.5 x 4.5) - 40
6 ( 20.25) - 40
121.5 - 40
81.5
Answer:
40,000
Step-by-step explanation:
refer to attached.
the number 4 is found in the Ten Thousands (10,000) place
hence the number 4 has the value of
4 x 10,000
= 40,000
Answer:
I think b
Step-by-step explanation:
Answer: 4.25
16 / 2 = 8
34 / 8 = 4.25
16 is a right angle and needs to be divided by 2 so that the answer could be correct because 34/16=2.125
The computation of the equation shows.that x is -4 and y is 0.6.
<h3>How to calculate the value?</h3>
4x + 5y = -1
-5x - 8y = 10
The value of x and y will be calculated thus:
-5 × (4x + 5y = -1)
4 × -(5x - 8y = 10)
-20x - 25y = 5
-20x -32y = 40
Add the equation
57y = 45
y = 45/75 = 0.6
Since 4x + 5y = -1
4x + 5(0.6) = -1
4x + 3 = -1
x = -1 - 3
x = -4
