Answer:
m∠I = 45.2°
Step-by-step explanation:
From the picture attached,
By applying cosine rule in in ΔHIJ,
Cos(∠I) = 
= 
= 
m∠I = 
= 45.21
= 45.2°
Therefore, 45.2° will be the correct option.
Lenth x width x height = the area and if you want to find the height then devide the area by the base
Answer:
x = -7
, y = 5 thus D)
Step-by-step explanation:
Solve the following system:
{4 x - 4 y = -48 | (equation 1)
5 x - 6 y = -65 | (equation 2)
Swap equation 1 with equation 2:
{5 x - 6 y = -65 | (equation 1)
4 x - 4 y = -48 | (equation 2)
Subtract 4/5 × (equation 1) from equation 2:
{5 x - 6 y = -65 | (equation 1)
0 x+(4 y)/5 = 4 | (equation 2)
Multiply equation 2 by 5/4:
{5 x - 6 y = -65 | (equation 1)
0 x+y = 5 | (equation 2)
Add 6 × (equation 2) to equation 1:
{5 x+0 y = -35 | (equation 1)
0 x+y = 5 | (equation 2)
Divide equation 1 by 5:
{x+0 y = -7 | (equation 1)
0 x+y = 5 | (equation 2)
Collect results:
Answer: {x = -7
, y = 5
Answer:
so the sides would have to be equal for all sides
2x-3=3x-8 -3=x-8 x=5
x-12, 4x-1, neither, or both?
2x-3=x-12 x-3=-12 x=-9
4x-1=3x-8 x-1=-8 x=-7
2x-3=4x-1 -3=2x-1 -4 = 2x x=-2
3x-8=x-12 2x-8=-12 2x=-4 x=-2
So the answer is neither or C
Answer:
x=2, -4
Step-by-step explanation:
The equation is 
. The x-intercept is the point(s) where the function intersects the x axis, so this value can be found by plugging in 0 for y. doing so results in 
. Then, solve for x by moving 18 over, dividing by -2, square rooting both sides, and subtracting 1 to find the value of x.
