Answer:
y = 28
Step-by-step explanation:
since this is an Isosceles triangle (x - 5)° must be equal to 34°
x - 5 = 34
x = 39
the sum of interior angles in a triangle is equal to 180°
if the two angles 34 + 34 = 68
Then the third angle is 180 - 68 = 112°
4y = 112
y = 28
Step 2: <span>Inverse Property of Addition
</span><span>any number added to its opposite will equal zero
</span>in this case + 20 - 20 = 0
answer
Inverse Property of Addition
Y=x-2

Answer:
Step-by-step explanation:
Given that,
The height of the tree, h = 14 ft
The height of the shadow, b = 16 ft
We need to find the angle of elevation of the sun from the ground. Let the angle be θ. We can use trigonometry to find it. So,
So, the required angle of elevation of the sun is equal to 
.
Answer : C
we need to the value of f(–1)
Table is given in the question
From the table ,
f(x) = 4 when x= -5, that is f(-5) = 4
f(x) = 0 when x= -1, that is f(-1) =0
f(x)= -1 when x=6, that is f(6) = -1
f(x)= -3 when x=9, that is f(9) = -3
So, the value of f(–1) = 0
