Answer:
92 cm
Step by step explanation:
first: you divide the rectangle into two right angled triangles using the diagonal
secondly:
you use pythagoras theorem to find the width of the rectangle
110²= 60²+ w²
w²= 110²- 60²
w²= 12100- 3600
w²= 8500
w= 92.195
w= 92 cm
X² - 16x =23
16/2= 8; 8²=64 add 64 to both sides of the equation
x² - 16x + 64 = 23 + 64
the answer is D.
Answer:
C=2
Step-by-step explanation:
-8(17-12)= -8(5)= -40
then
-2(8-(-2))= -2(10) = -20
so then
-40/-20
=-2
