Answer: 50
Step-by-step explanation: 83.75*100 / 67 = 125 which is n ,
125 * 40/100 = 50
The key to this question is
"exactly one pair"
every shape stated has more than one pair except for the trapezoid
(which has just one)
Factoring:
FOIL (first, outer, inner, last) method
(a+b)(c+d) = 0
ac+ad+bc+bd = 0
Zeros:
(x+a)(x+b) = 0
x+a = 0, x= 0-a
x+b = 0, x= 0-b
Answer:
x = 15
arc PQ = 110°
ΔPQR is an acute triangle
Step-by-step explanation:
(6x) + (8x-10) + (10x+10) = 360°
combine like terms:
24x = 360°
x = 15
arc PQ = 8(15) - 10° = 110°
The answer is A) AAS because it goes angle then angle then side.
