The angle of a tangent and a radius is a right angle.
The missing length would be the hypotenuse. Use the Pythagorean theorem to solve.
X = SQRT(12^2 + 16^2)
X = SQRT(144 + 256)
x = SQRT(400)
X = 20
Answer:
if by decomposition you mean breaking it into parts then
break it into 2 triangles and 1 rectangle
left to right
triangle with base y and height h
h=10
y=3
area of triangle=1/2bh
area=1/2(10)(3)
area=5(3)
area=15
rectangle of length x and height h
area= length times width
x=8
h=10
area=8 times 10
aera=80
last triangle
should be same as other since same base (y) and same height (h)
15
add
15+80+15=120
Step-by-step explanation:
Answer:
7b - 7
Step-by-step explanation:
You can use distributive property which is x (a + b) = x*a + x*b and x (a - b) = x*a - x*b. Therefore, the expression is 2*b + 2*4 + 5*b - 5*3 which is:
2b + 8 + 5b - 15, which is, if you combine like terms:
7b - 7
This graph should help find the coordinates you need that was made of this inequality!
