Rectangular book
two 8 1/2 sides
two 9 1/4 sides
8 1/2*2=17
9 1/4*2=18 1/2
17+18 1/2= 35 1/2
The perimeter of the textbook is 35 1/2 inches or 35.5 inches.
Hope this helps :)
Ur close but it is 0.023 you were off just a bit
Answer:
x = 34
Step-by-step explanation:
∠ PSR and ∠ TSU are vertical angles and congruent, then
∠ PSR = 4x, thus ∠ PSQ = x
The exterior angle of a triangle is equal to the 2 opposite interior angles.
∠ SQR is an exterior angle of Δ PQS , thus
x + x = 68
2x = 68 ( divide both sides by 2 )
x = 34
M = (y2 - y1) / (x2 - x1)
1/4 = (5-3) / (r +4)
1/4 = 2/ (r + 4)
Cross multiply
2*4 = r + 4
8 = r + 4
Subtract 4 from both sides
4 = r
CHECK
(-4,3)(4,5)
m = (5-3)/(4--4) = 2/8 = 1/4
