First, we need to find the base. To do so, we will need to use the Pythagorean Theorem on one of the smaller triangles to solve for its unknown side. Then, we can double the base of the one to find the base of the whole.
Pythagorean Theorem: a^2 + b^2 = c^2
(12)^2 + b^2 = (16)^2
144 + b^2 = 256
b^2 = 112
b = 
b = 
total base = 2 x = 
Second, we can find the area. The formula for the area of a triangle is A = 1/2 x base x height.
A = 1/2 x x 12
A = x 12
A = 
units^2
Third, we can find the perimeter. The perimeter is the sum of all of the exterior sides.
P = 16 + 16 +
P = 32 + units
Hope this helps!! :)
If I'm right it could be C. IF I'M RIGHT, I'm not totally sure but I hope this helps.
Answer: the value of x is 1
Step-by-step explanation:
if you use x by itself it is = to 1
(hope this helps)
Answer:
C
Step-by-step explanation:
When reflecting around the x axis, the x value stays the same and the y- will change.
Answer:
b = 4
, c = 8
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin30° = 
, then
sin30° = 
= 
= ( cross- multiply )
c = 8
Using Pythagoras' identity in the right triangle
b² + 4² = 8²
b² + 16 = 64 ( subtract 16 from both sides )
b² = 48 ( take the square root of both sides )
b = 
= 
= 4
