Answer:
B) 34°
Step-by-step explanation:
Answer:
y = 11
x = 8.6
Step-by-step explanation:
The small triangle with 30,32,y looks like right triangle
so according to formula a^2 + b^2 = c^2
so 30^2 + y^2 = 32^2
900 + y^2 = 1024
y^2 = 124 => y = 11
The larger triangle also looks like a right triangle
so according to formula a^2 + b^2 = c^2
(30 + 10)^2 + 22^2 = (32 + x)^2
1600 + 44 = (32 + x)^2
so (x + 32)^2 = 1644
x + 32 = 40.55
x = 40.55 = 32 = 8.55 = 8.6

Because according to PEMDAS, Parenthesis always start first
Answer:
y = -3/8(x + 2)^2 + 8
Step-by-step explanation:
vertex form is
y = a(x - b)^2 + c where a is a constant and (b,c) is the vertex.
The maximum is at (-2, 8) because x 8 = height and x =-2 is equn. of symmetry
So here we have
y = a(x - (-2))^2 + 8
y = a(x + 2)^2 + 8
Now at the point (-6, 2):
2 = a(-6+2)^2 + 8
2 = 16a + 8
16a = -6
1 = -3/8.
So our equation is y = 3/8(x + 2)^2 + 8
AB=DE is a true statement
