Question

PLEASE help me with this :((

Answer 1

Problem 1

Answer: True

Step-by-step explanation:

Since
`WV+VU \\e 12`,

we can set up this equation

WV + VU = 12 + k

where k is nonzero

If k = 0 happened, then we'd land on WV+VU = 12. So we want anything but k = 0.

Let's plug in VU = 5 and see what happens

WV + VU = 12 + k

WV + 5 = 12+k

WV = 12+k-5

WV = 7+k

This shows the connection of
`WV+VU \\e 12 \text{ and } VU = 5` leading to
`WV \\e 7`

=================================================

Problem 3

Answer: True

Step-by-step explanation:

Angle A = 100 degrees, which leaves 180-A=180-100 = 80 degrees to be split amongst the two remaining angles of triangle ABC.

This leftover amount (80) is not larger than 90. So there is no way to have angle B = 90

It turns out that any obtuse triangle cannot have a 90 degree angle. The other two angles must be acute.

Summary: Both answers are True
