Answer:
D) 20.
Step-by-step explanation:
First find the value of x using Pythagoras theorem:
10^2 = x^2 + (2x)^2
5x^2 = 100
x^2 = 20
x = √20
= 2√5.
So the area of triangle
= 1/2 * base * height
= 1/2 * 2x * x
= x^2
= (2√5)^2
= 20.
Answer:
a) None
b) (0, -2)
Step-by-step explanation:
The x-intercept is the point at which the line cuts through the x-axis, while the y-intercept in the point at which the line cuts through the y-axis.
a) The line does not cut through the x-axis, thus it has no x-intercept.
b) The line cuts through the y-axis at y= -2, making its y-intercept (0, -2).

hope this helps good luck have a good nite hope u enjoy ur the rest of ur weekend
Answer:
m= 2 / 3 b= -2
Step-by-step explanation:
you have to look at the graph to find the y-intercept
then do this to find the slope
m =
y2 - y1
x2 - x1
you plug in all the numbers to get
m=
<u>0+4</u>
3+3
(it would be 3 minus, negative 3 which looks like: 3- - 3 becomes 3+3)
m=
<u>4</u>
6
and simplified that would be
m= 2/3
Answer:
x=19.2
Step-by-step explanation:
sin(28)=9/x
x=9/sin(28)
x=19.2
