Choice A is correct
BC=DC
the two triangles share one angel C
the two triangles each have a right angle
so they are congruent according to Angle-Side_Side Theorem
Answer:
h=12 A=144 sq. cm.
Step-by-step explanation:
pythagoream therom:
9^2+h^2=15^2
81+h^2=225
h^2=225-81
h^2=144
Sq. rt h^2=sq. rt 144
h=12cm
1/2(b1+b2)h
1/2(5+19)12
1/2(24)12
1/2(288)
a=144
Answer:
x = 16
angle K = 77
angle L = 87
angle M = 16
Step-by-step explanation:
Mathematically, the sum of interior angles of a triangle is 180 degrees
Thus:
(5x-3) + (6x-9) + x =180
12x -12 = 180
12x = 180+12
12x = 192
x = 192/12
x = 16
Angle K = 5x-3 = 5(16)-3 = 80-3 = 77
Angle L = 6(16)-9 = 96-9 = 87
Lastly;
angle M = 16 degrees
Answer:(4,1)
Step-by-step explanation: the function is goin up by 0.5/1. In other words it has a slope of 0.5. 4,1 dosent go with that pattern
