A triangle with sides of 2, 3, and 4 is an obtuse triangle. T/F

True

Step-by-step explanation:

We actually can use Sine, Cos, or Tangent to solve for the angles, which would give the angle, but graphing it came up with an Obtuse Scalene triangle.

A. (–4.5, –2.5)

C. (7.9, 9.5)

E. (1.3, 3.5)

Step-by-step explanation:

Given

y=1.5+ ⌈x⌉

We have to find the points which satisfy the given equation

So,

A. (–4.5, –2.5)

Putting in function

-2.5 = 1.5 +  ⌈-4.5⌉

Applying the ceiling function on -4.5 gives us: -4

-2.5 = 1.5-4

-2.5 = -2.5

B. (–0.8, 0.5)

0.5 = 1.5 +  ⌈-0.8⌉

0.5 = 1.5 + 0

0.5 ≠ 1.5

C. (7.9, 9.5)

9.5 = 1.5 + ⌈7.9⌉

9.5 = 1.5+8

9.5 = 9.5

D. (4.5, 6)

6 = 1.5 + ⌈4.5⌉

6 = 1.5+5

6 ≠ 6.5

E. (1.3, 3.5)

3.5 = 1.5+⌈1.3⌉

3.5 = 1.5 + 2

3.5 = 3.5

Therefore, Options A, C and E are correct ..
