Answer: acute angles are higher that 0° and smaller than 90°
Step-by-step explanation: obtuse are between 90° and 180°
Answer:
did that first one its false
A= 53, B= 100, C= 27 (the last option)
BC is the longest side because it is opposite the largest angle ( not true)
14x + 10y = 72
14x + 4y = 96
6y = -24
6 6
y = -4
14x + 10y = 72
14x + 10(-4) = 72
14x - 40 = 72
+ 40 + 40
14x = 112
14 14
x = 8
(x, y) = (8, -4)
Answer: 119 4/7
Step-by-step explanation:
Add all the sides together.
X^2-10x-24=0
(x+2)(x-12)=0
x=-2 or x=12
