Answer:
Remember that a triangle's area is bh/2, where
b = base
h = height
So. You start with a triangle of base b and height h, add 2 to the height, and get a triangle of area 82.5.
b(h+2)/2 = 82.5
b(h+2) = 165
What you want to do from here is test the b and h from the choices given, and figure out which b and h satisfy this.
(a) If b=13 and h=15, b(h+2) = 221 nope.
(b) If b=9 and h=11, b(h+2) = 117 nope.
(c) If b=11 and h=13, b(h+2) = 165 that's it!

Answer:
The statue is 12 meters taller than Anakka.
Step-by-step explanation:
Use the Pythagorean Theorem which is a^2+b^2=c^2. The length is b. You know that the statue in Dover Park is 16 miles away so that is b. You know that the hypotenuse is 20 so that means the equation will be a^2+16^2=20^2. Simplify this to get a^2+256=400. Simplify this to get a^2=144. Divide each side by squared so that means a=square root of 144 which is equal to 12. Therefore, the statues is 12 meters taller than Anakka.
Answer:
∠2=92°
Step-by-step explanation:
Using an angle formula, -8x+144=2x+74
Simplification:
-8x+144=2x+74
-8x+70=2x
70=10x
x=7
Therefore, each angle is 88°
Now, because ∠2 is adjacent to one of 88°, they add up to 180°
Therefore,
180°=88°+∠2
∠2=92°
The answer for the question is b
Answer:
y = 10/3x - 2/3
Step-by-step explanation:
10x-3y=2
-3y = -10x + 2
-3y/-3 = -10x/-3 + 2/-3
y = 10/3x - 2/3
