An isosceles triangle has two sides of equal length, a, and a base, b. The perimeter of the triangle is 15.7 inches, so the equa

tion to solve is 2a + b = 15.7.
Which lengths make sense for possible values of b? Check all that apply.

B must be between (15.7 - 2a) and (15.7 + 2a)
(15.7-2a) < b , (15.7+2a). It cannot equal either length.

If angle P is a right angle and angle P and Q from a linear pair, then angle Q is

anygoal [31]

< P is a right angle.....a right angle is 90 degrees.
< P and < Q form a linear pair....a linear pair, when added, = 180 degrees

so if < P is 90.....and when added to < Q = 180...
90 + Q = 180
Q = 180 - 90
Q = 90 <== so < Q is also a right angle...measures 90 degrees
