Tell whether a triangle can have sides with lengths 3, 4, and 8.

Vadim26 [7]

Answer:

Yeah a triangle can have any measurements as long as it makes sense. Your not gonna put the mesurment 8 on the shortest side but the longest, and then the next longest will be 4, and then 3 as the shortest.

Step-by-step explanation:

You'd be lookin for a scalene triangle, Acute triangle, or obtuse triangle, (I'm not so sure about a right triangle, but you might be lookin at that too)

I hope this helps!!!!

PY=2, HP=3, find HY Geometry

klemol [59]

Answer:

$HY=\sqrt{5}\ units$

Step-by-step explanation:

we know that

The triangle HPY is a right triangle (because the angle ∠HYP is a right angle)

Applying the Pythagorean Theorem

$HP^2=HY^2+PY^2$

substitute the given values

$3^2=HY^2+2^2$

Solve for HY

$9=HY^2+4$

$HY^2=9-4$

$HY^2=5$

$HY=\sqrt{5}\ units$

ZB is 3x-5 BA is x+3

Akimi4 [234]

If B is the midpoint of ZA, then ZB = BA
3x-5 = x+3
3x - x = 3 + 5
2x = 8
x = 8/2
x = 4

ZA = ZB + BA
= 3x-5 + x+3
= 3*4 - 5 + 4 + 3
= 12 - 5 + 7
= 14

Answer: D. 14
