Answer:
The triangle is acute because all of the angles are less than 90º
Answer:
Step-by-step explanation:
3x + 2 + 58 = 90
3x + 60 = 90
3x = 30
x = 10
it's adjacent
Answer:
D
Step-by-step explanation:
This is isosceles triangle
So, y = 53 {angles opposite to equal sides are equal}
53 + 53 + x = 180 {Angle sum property of triangle}
106 +x = 180
Subtract 106 from both sides
x = 180 - 106
x = 74
P(-2) = 12
p(x) = x^2 - 4x
= -2^2 - 4(-2)
= 4 + 8
= 12
