Not sure what do with the other numbers? Like the -2/5
Maybe put them instead of the 2/3?
Answer:
22.7604763 degrees
Step-by-step explanation:
Note that the answer is NOT 20 degrees.
She adjusted the ramp to half the original <em>incline</em>
Therefore we have tan 40 = x = 0.839099631.
We want an incline of y degrees where tan y = x/2 = 0.839099631/2 = 0.419549815
Taking the arctan of both sides, we get
y = arctan(0.419549815) = 22.7604763 degrees
The value of x when the triangle and the parallelogram have the same area is 6 units
<h3>The dimensions</h3>
The dimension of the parallelogram is given as:
The dimension of the triangle is given as:
<h3>Areas</h3>
The area of a shape is the amount of space it occupies
The area of the parallelogram is calculated as:

The area of the triangle is calculated as:


Both areas are equal.
So, we have:

Divide both sides by x

Subtract 4 from both sides

Hence, the value of x is 6 units

X=0 (4×0)+3=3 that I think is the absolute value
Answer:
I think it would all of them, I could be wrong though
Step-by-step explanation:
To find if one of these is a correct triangle you would need the sum of 2 sides to be longer than the third
A: ⇒ 4 + 9 > 7
B: ⇒ 5 + 12 > 13
C: ⇒ 20 + 22 > 24
therefore making A, B, and C the answer.
let me know if I'm wrong >:3
